They’ve had some issues with that though. lemmynsfw was heavily defederated from others over concerns about CSAM being federated, and after that lemmynsfw had much more mild porn.

Personally, I think that as long as porn is still freely available via old reddit without logging in, then it won’t take off much. Also, we’re in the post-Only Fans age, so it’s unlikely lemmy will ever get that “pure” gonewild feel that reddit had, as almost every user that posts their own porn is now doing it for money.
