If it sounds like AI-generated spam, it probably is.
No, I can't give you an exact guideline on that, but no human woman has ever said "After I jerk my pussy 6-7 times a day I go out looking for a man brave enough to lick it but never find one". Titles like that are very clearly unnaturally generated.
We don't even need a new rule to ban these titles; the old spam rule works fine. This post is just a notification that we're going to start enforcing it for phrasing that seems clearly machine-generated.
If this is a problem for you-- i.e. if talking like a human seems hard-- you might be an AI?
