The accounts were probably banned because they were bots. Usually they are stopped by the YT (lack of a better word) Firewall. Every once in a while they get through and even post.....it's usually in the middle of the night and porn
But the Mods clean it up and delete the posts. It's also why there's a hold on new members posts before they are posted. I think it's 10....but I'm not sure. I reported the first one so they get a notification and I'm sure Ann will be along shortly to take care of it.
