deviantART allows pretty much anything, there's a little tab that you have to push for saying that it's mature and there's a button you have to push saying that it's AI generated, as long as you follow those two rules you can post pretty much anything as long as it isn't criminal activity.

The only downside is is that anybody who wants to view your material is going to have to have a deviantART account as well but it's free to view and you can just log in using your Google account.

So will be a little bit harder for someone to see your content but not so hard that people will give up.
