Will the warn level ever go down? Just curious.

Not to my knowledge. Some forums decrease it after a set time, but for now, you're stuck with it. Just don't break any more rules and you should be fine. ^^

Okay but to tell you the truth, I don't remember posting anything on spam bots or whatever. I think my brother has been on and trying to get me banned. He's doing that. I saw him once one here on typing something but I stopped him.

Right. Well, you will be held responsible for all posts your account makes, regardless if whether it is you or your brother that posts it. I suggest you tighten security measures if you want to keep your brother out of your account.
