Remove anonymous poster content from Tumblr

Why this happens on Tumblr

• Tumblr reblogs create persistent copies of content across hundreds of unrelated blogs. A single original post can have thousands of reblogs, each requiring a separate URL in the takedown notice.
• Truly anonymous posting is uncommon. Most anonymous accounts produce identifiable metadata through account creation, payment for premium features, IP address logs, and device fingerprinting.
• The poster is typically someone the victim knows. Statistical analysis of anonymous NCII cases shows that over 80 percent of perpetrators are eventually identified as known personal connections of the victim.
• Cross platform spread is the rule, not the exception. Content first appearing on Tumblr 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. The anonymous account's username, posting history, and any biographical details disclosed in posts or comments
2. 02
   Run a biometric scan to find every copy across platforms Content first appearing on Tumblr 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 Tumblr Tumblr accepts NCII reports through its content removal form and through its DMCA agent. The platform's 2018 adult content ban remains in effect, which means NCII reports also benefit from policy enforcement against any sexual content.
4. 04
   Preserve identification metadata for subpoena Even anonymous accounts produce identifiable metadata through Tumblr. 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
   Notify Google and Bing for search deindexing Search engine deindexing runs in parallel to platform removal. Even after the original is removed, search engines retain cached thumbnails and snippets for weeks. File NCII removal requests with both Google and Bing alongside the platform notice.
6. 06
   File a police report and preserve the legal record 47 USC 223a TAKE IT DOWN Act for platform removal regardless of poster identity 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

• Tumblr is owned by Automattic and has historically been responsive to NCII reports. The combination of the adult content ban policy and the TAKE IT DOWN Act gives multiple grounds for removal of any reblog chain.
• 47 USC 223a TAKE IT DOWN Act for platform removal regardless of poster identity
• Doe defendant filings to preserve civil claims while identification proceeds
• Capture the original post URL, the original blog name, and as many reblog URLs as possible. Tumblr's reblog graph is queryable through its API which enables batched removal requests for known reblog chains.
