The combined situation

Dezgo is a free Stable Diffusion service that does not require account creation. No filtering on explicit content makes it a frequent source of NCII. When Dezgo output appears on Mastodon, 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

No account requirement and no content filtering make Dezgo a significant entry point for casual NCII creation. On Mastodon specifically, 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.

How removal proceeds

Mastodon is federated across thousands of independent instances. Removal requires identifying the specific instance hosting the content and contacting that instance's admin directly. Source attribution to Dezgo is documented through dezgo uses standard stable diffusion variants without custom finetuning, which strengthens the takedown notice and supports parallel legal action.
