The combined situation

Nudify.online is a freemium nudify service that allows three free outputs per day per IP. The pay tier removes watermarking and increases output resolution. When Nudify.online output appears on Tumblr, removal proceeds through the statutory takedown process under 47 USC 223a combined with source attribution to strengthen the legal claim.

Why this combination is high risk

Nudify.online has no terms of service, no contact information, and no age verification. The service is accessible from school networks in most United States districts because it has not been added to standard content filtering blocklists. On Tumblr specifically, 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.

How removal proceeds

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. Source attribution to Nudify.online is documented through free tier outputs carry a faint nudify watermark in the lower right corner, which strengthens the takedown notice and supports parallel legal action.
