Are there any social media sites where AI is effectively banned? I know it's not an easy problem but I haven't seen a site even try yet. There's a ton of things you can do to make it harder for bots, ie analyze image metadata, users' keyboard and mouse actions, etc.
Not actually banned on Bluesky, but the community at large is so hostile to it that, generally, there's very little AI stuff.
Apparently the vine restart will explicitly ban ai content. Thus providing an excellent source of untainted training data, but that's beside the point
There are mastodon communities such https://mastodon.art/ where AI is explicitly banned.
in effect, broadly anti-AI communities like bsky succeed by the sheer power of universal hate. Social policing can get you very far without any technology I think
I don't know of any, but my strategy to avoid slop has been to read more long-form content, especially on blogs. When you subscribe over RSS, you've vetted the author as someone who's writing you like, which presumably means they don't post AI slop. If you discover slop, then you unsubscribe. No need for a platform to moderate content for you... as you are in control of the contents of your news feed.
The said hypothetical social media, if gaining any traction, will be the heaven for adversarial training.
