Ok, i found another AntiPoints Bug (I found 1 yesterday), which is quite small but still a bug :

When user post a message he got this AntiPoints status near his nickname. If you click on it, then it says something like "Username has some possitive AntiPoints.", right?

Ok, now... there are people who post messages and banned after that. take those posts, or hidden posts (is it the same thing? never mind).
Click on the AntiPoints status of the banned user, can you see the message? good. now click on the "To view this post click [here]" link, to see the message.

A new window will be opened. Click on the AntiPoints status on the new window

"Username has AntiPoints."
There you go.
