Remove paste site leak content from Mastodon

Why this happens on Mastodon

• Federated content spreads across multiple instances through reposts and replies. Removing from the originating instance does not remove from the cached copies on every instance that federated the post.
• Paste sites are used as low cost distribution indexes pointing to content hosted elsewhere. The original paste serves as a lookup that survives even when the underlying linked content is removed.
• Paste site operators generally comply with NCII removal requests when properly notified. Pastebin, Ghostbin, and similar services have established abuse contacts and respond within 48 hours typically.
• Cross platform spread is the rule, not the exception. Content first appearing on Mastodon typically reaches between four and twelve additional platforms within 72 hours through reposts, mirrors, and screenshot redistribution.

The takedown process

What to do, step by step

1. 01
   Document every instance before reporting Capture full page screenshots with the URL bar visible, the posting account handle, and the upload timestamp. Full page screenshot of the paste, including the URL and any associated metadata
2. 02
   Run a biometric scan to find every copy across platforms Content first appearing on Mastodon rarely stays there. ScanErase indexes 2.4 billion face embeddings across 200 plus platforms and identifies every current hosting location in a single scan, including AI generated derivatives.
3. 03
   Dispatch the takedown notice to Mastodon Mastodon is federated across thousands of independent instances. Removal requires identifying the specific instance hosting the content and contacting that instance's admin directly.
4. 04
   Preserve identification metadata for subpoena Even anonymous accounts produce identifiable metadata through Mastodon. Account creation IP, device fingerprint, and posting history support law enforcement subpoena to identify the perpetrator. Doe defendant filings preserve civil claims while identification proceeds.
5. 05
   Escalate through hosting and CDN if required Each Mastodon instance has its own admin. Most instance admins are responsive to NCII reports. The fediverse operates a shared block list which can prevent the originating instance from federating with mainstream instances.
6. 06
   File a police report and preserve the legal record 47 USC 223a TAKE IT DOWN Act for the linked NCII content provides the federal basis for the takedown. Document every notice sent, every platform response, and every removal confirmation in a single evidence file. ScanErase produces this Verified Removal Package automatically as your case progresses.

Legal context

• Most Mastodon instance admins comply quickly with NCII reports. The Mastodon Server Covenant explicitly prohibits NCII content, which gives leverage even with instances outside US jurisdiction.
• 47 USC 223a TAKE IT DOWN Act for the linked NCII content
• DMCA Section 512 against the paste site operator
• Capture the full federated URL including the instance domain, the original post URL, and any reblogs from other instances. Each instance must be reported separately for full removal.
