Solutions · Reputation defense · Tamper-evident social evidence

Capture posts, reviews, and profiles — before they're deleted, edited, or denied.

Posts get edited, comments get hidden, accounts vanish, and screenshots are dismissed as fake. GetProofAnchor preserves the moment in a portable Evidence ZIP and shareable Proof ID, anchored in four independent integrity layers — so any later modification is provably detectable: Match / Modified.

Capture before it vanishes

Public posts via the dashboard, login-protected content via the browser extension.

Survives deletion

Evidence remains valid even after the post, comment, or entire account is deleted.

Verifiable forever

Offline-verifiable by any forensic expert with python3 + openssl + ots — even years later.

What this is: an evidence-preservation workflow for online reputation cases — cryptographic integrity verification + EU-qualified timestamp + Bitcoin anchor. The captured evidence remains valid even if the original content, profile, or platform disappears.

What this is not: legal advice, content moderation, takedown service, or a guarantee of court admissibility. Admissibility depends on jurisdiction and circumstances.

Reputation-defense workflow
3-minute workflow

Designed for the “the post never existed” and “your screenshot is doctored” arguments.

Step 1 — Capture before it disappears

Public URL via the dashboard, or login-only content (private profiles, paid platforms, restricted forums) via the browser extension — exactly as your real browser shows it.

https://social.example.com/post-or-profile
Step 2 — Export Evidence ZIP

Self-contained, offline-verifiable bundle: full-page screenshot + captured DOM + extracted text + SHA-256 manifest + hash chain entries + Bitcoin OpenTimestamps receipt + eIDAS qualified-timestamp kit + bilingual verification README.

Step 3 — Share or verify
Proof ID: 70352d57-d6bc-4873-87f2-d052b1bef548

Share the Proof ID URL with PR, legal, or platform trust-and-safety teams. Verification is deterministic: Match (intact) or Modified (per-layer report). Works online or fully offline.

Works for: tweets/posts, comments, replies, profile pages, reviews, ratings, forum threads, story screenshots, news comment sections, paid-platform posts.

What reputation teams capture with GetProofAnchor

Built around content that disappears or shifts the moment a dispute escalates — the exact moment evidence becomes critical.

Deletable social posts

X/Twitter, Facebook, Instagram, LinkedIn, TikTok, Threads — content that authors can edit or delete the moment pressure starts.

Reviews & ratings

Google, Yelp, TrustPilot, Glassdoor, App Store, Booking, TripAdvisor — false or defamatory reviews that vanish during dispute or moderation.

Comment threads & forum posts

Reddit, Discord, news-site comments, niche forums — pile-on comments and coordinated harassment threads that often get deleted en masse.

Personal attacks & smears

Posts targeting an individual or executive — including ones quietly removed once challenged or reported.

Coordinated harassment

Brigading, dog-piling, mass replies, screenshots being reposted out of context — captured at the moment they occur, not after the platform cleans up.

Fake quotes & misattribution

Fabricated screenshots, false attribution of statements, misattributed quotes — preserved with the actual URL and capture metadata showing the original context.

Why this evidence holds up after the post is gone

A plain screenshot is easy to dismiss as fake — and once the original post is deleted, you have nothing to compare it to. GetProofAnchor anchors every capture in four independent integrity layers, and three of them keep working even if the post, profile, or entire platform disappears.

Layer 1
SHA-256 file manifest

Every file in the Evidence ZIP has its hash recorded in manifest.json. Editing a single byte — even reformatting whitespace — fails the integrity check.

Layer 2
Append-only hash chain

Each capture is part of a global SHA-256 chain. Each entry contains the hash of the previous one, so inserting or modifying a past entry breaks the chain mathematically.

Layer 3
Bitcoin OpenTimestamps anchor

The chain head is anchored to the Bitcoin blockchain. Once confirmed, the timestamp is preserved by the entire Bitcoin network — independent of GetProofAnchor and of any social platform.

Layer 4
eIDAS qualified timestamp

RFC 3161 timestamp from an EU-qualified Trust Service Provider (currently SK ID Solutions, Estonia). Recognized as legal-grade proof of existence at a point in time under Regulation (EU) 910/2014.

All four layers PASS → the package is cryptographically intact, not just believable. Any layer FAILS → modification is detected, with a per-layer report showing exactly which one was tampered with.

Why a screenshot dies the moment the post is deleted

In reputation disputes, the opposing side's first move is to delete or edit the original. After that, your screenshot is just a pixel array against their claim that “it never said that.” Without an integrity mechanism and an independent time anchor, a screenshot proves nothing about when or whether the content existed.

Cryptographic integrity verification

Evidence ZIP includes a SHA-256 manifest of every file. Subsequent edits — text, screenshot pixels, file replacement, even JSON whitespace reformatting — become mathematically detectable. No need to trust the screenshot alone.

Two independent time anchors

Each proof gets two independent time anchors: an eIDAS qualified timestamp (legally recognized in EU/EEA) and a Bitcoin OpenTimestamps anchor (preserved by the Bitcoin network). The post can be deleted, the account can vanish — both anchors keep working.

What's inside the Evidence ZIP

A standardized, self-contained bundle of around 24 files (format: getproofanchor-evidence-1). Designed to be stored, sent to PR or legal teams, attached to platform takedown requests, or handed to a forensic expert for independent verification.

  • manifest.json — the integrity baseline — SHA-256 hash of every other file in the package
  • proof.json — main record — Proof ID, source URL, final URL, capture time, SHA-256 fingerprints, eIDAS status, Bitcoin anchor info
  • screenshot.png — full-page screenshot at capture time (the visible state of the page)
  • page.html + content.txt — captured DOM/HTML and extracted plain-text content
  • capture/capture_meta.json — forensic capture metadata — engine, viewport, scroll, consent dialogs auto-handled
  • chain/* — append-only hash chain entries linking this proof to the global chain
  • anchor/anchor_receipt.ots — binary OpenTimestamps receipt with the Bitcoin merkle path
  • timestamp/* — complete eIDAS qualified-timestamp kit — RFC 3161 token, TSA certificate chain, frozen EU Trusted List snapshot, verification report
  • report.pdf — human-readable Evidence Report PDF — formatted summary suitable for sharing with PR, legal, or platform teams
  • README.md — bilingual (EN + CS) verification guide with copy-paste commands using python3, openssl, ots
Verifier outcome: Match / Modified.

eIDAS qualified timestamp — what it adds in reputation cases

Every GetProofAnchor proof receives an RFC 3161 timestamp from an EU-qualified Trust Service Provider. This is not a marketing label — it has specific legal meaning under Regulation (EU) 910/2014 (eIDAS) and gives your evidence a defensible time anchor in the EU and EEA, even when the original platform is uncooperative or the content is gone.

Qualified provider

Currently SK ID Solutions AS (Estonia), listed on the EU Trusted List as a Qualified Trust Service Provider.

Legal recognition

Recognized in EU/EEA courts and regulatory proceedings as proof of existence at the timestamped moment, with no need to trust GetProofAnchor or the original platform itself.

Independence over time

The full TSA certificate chain and a frozen snapshot of the EU Trusted List are inside the ZIP — verification works offline, even years later, even if the TSA later ceases operation.

Combined with the Bitcoin OpenTimestamps anchor, you get two independent time anchors — one legally recognized, one cryptographically global — backing the same evidence, even after the original post is deleted.

Common questions about reputation evidence

Direct answers to the questions we hear most often. Tap to expand.

Can you capture a post that has already been deleted?
No. GetProofAnchor cannot retrieve content that no longer exists publicly — there is no archive of every page on the internet. The product is designed for capturing content while it is still visible, before it is deleted, edited, or the platform makes it inaccessible. The earlier you capture, the stronger the evidence.
How is this better than just taking a screenshot?
A screenshot can be edited in seconds with any image tool, and the opposing side will argue exactly that. GetProofAnchor wraps the screenshot, captured DOM/HTML, extracted text, and capture metadata in a four-layer cryptographic trust stack: SHA-256 file manifest, append-only hash chain, Bitcoin OpenTimestamps anchor, and eIDAS qualified timestamp. Subsequent modification of any byte fails the integrity check, and the timestamp is verifiable independently of GetProofAnchor.
Can it capture content behind login (private accounts, paid platforms, restricted forums)?
Yes — that is what the browser extension is for. Available on Enterprise and Business plans, the Chrome extension captures exactly what your real browser is showing, including content that requires login, 2FA, paid subscription, or membership. Public profiles and posts can also be captured server-side via the dashboard.
What about deepfakes, manipulated images, or fake quotes attributed to me?
GetProofAnchor preserves the published state of the content — it does not authenticate the truthfulness of what someone else posted. But that is exactly what reputation cases need: a verifiable record proving that at time T, the URL X publicly displayed content Y. Whether the content is true or false is then a separate legal/factual question, but the existence and exact form of the post is no longer disputable.
Will the evidence still work if the platform removes the post or the user deletes their account?
Yes. The Evidence ZIP is fully self-contained and verifiable offline. The eIDAS qualified timestamp and Bitcoin OpenTimestamps anchor are independent of the social platform — they remain valid even if the post is deleted, the account is suspended, or the platform itself shuts down. That is the entire point: capture once, prove forever.
Is this useful in defamation, harassment, or cyberbullying cases?
GetProofAnchor is not a legal service and does not provide legal advice or guarantee admissibility — that depends on jurisdiction and the specific case. What it provides is the kind of tamper-evident, time-anchored record your lawyer or platform-trust-and-safety team will need: bilingual Evidence ZIP with cryptographic integrity, eIDAS qualified timestamp recognized in EU/EEA under Regulation (EU) 910/2014, and an offline verification kit for forensic experts.
