Certify defamatory and harmful content before it disappears
Defamatory content is most often removed the moment the author realises legal action is on the table. Certify the page, post, or review with a qualified RFC 3161 timestamp first — a signed PDF of what was published, the URL, and the moment of capture.

Why a screenshot is not enough.
Defamation cases turn on three facts: what was said, to whom, and when. A screenshot establishes none of these to a forensic standard.
✗
The URL is not bound to the screenshotAnyone can write a URL into a graphic. A certificate binds the URL the browser actually resolved.
✗
No proof the page was online at that momentWithout a qualified timestamp, the "when" is your word against theirs.
✗
Engagement counts and replies are missingRepublication, comment threads, and shares matter for damages — screenshots crop them out.
✗
The defendant routinely claims fabrication"That screenshot is fake" is the standard defence. Cryptographic signatures answer it.
What a certified defamation package contains.

Full-page screenshot and HTML capture of the post or article at the moment of certification.

RFC 3161 timestamp

Metadata ZIP
Manifest, signature, public key — for independent verification by opposing counsel.
How to certify defamatory content quickly.
Speed matters. Each hour the content remains online increases harm but also increases the risk of deletion.
1
Copy the direct URL of the postNot the profile page — the canonical post URL.
2
Go to /certificates/newChoose a Website certificate (public posts) or Browser Session (logged-in only).
3
Capture and downloadThe package includes the signed PDF, metadata ZIP, and (for sessions) a video recording.
4
Send to your defamation lawyerThe PDF doubles as a contemporaneous record of harm and a foundation for a takedown notice.
How to capture each content type.
Social media post
Direct URL capture for public Facebook, X, LinkedIn, or Instagram posts; Browser Session for private posts or Stories.
Article or webpage
Use a Website certificate for news articles, forum threads, or blog posts published online.
Live interaction
For sessions where the post is being edited or interacted with, a Browser Session records everything.
Defamation-evidence questions, answered directly.
How do I preserve a defamatory post before it is deleted?
Open a website certificate at /certificates/new and submit the post URL immediately. The platform captures the full page, the URL, and a qualified RFC 3161 timestamp before the original can be removed.
What evidence is required for a defamation claim?
A defamation claim requires evidence that the statement was published, to whom, and when. A certified capture records the page exactly as it was served, with a verifiable timestamp — exactly what counsel needs to plead and prove publication.
Can I certify a defamatory tweet or Facebook post?
Yes. For public posts, a Website certificate captures the URL directly. For posts visible only to logged-in users, use a Browser Session — the recorded video and HAR show the post as it appeared.
What about deepfakes or AI-generated harmful content?
Same workflow: certify the page where the content is hosted. The certificate proves the page existed and what it contained at a specific time, which is the foundation of any defamation or NCII claim.
Is this legal advice?
No. This service creates technical evidence artifacts. Legal admissibility depends on jurisdiction and circumstances. Consult qualified legal counsel for advice specific to your situation.
Ready to certify?
The fastest path from defamatory post to admissible evidence is a certified capture, before the author deletes.
