Ban when IP changes

I saw someone get banned because his IP changed(IP not from the same country as the original one), are these kind of bans automatic?

Not sure, but here's a bump to help you find out.

lol i just got ban using utrasuft like wtf :|

Do you get a message that says "Your IP Address has been banned" or something like that when you go onto the site? That's the only way to indicate if you have been banned.

Since your using a proxy, some scammers might have used the same IP in the past, and those IPs might have been banned. So... Yea.
