Not sure what you mean. The only thing I can think of that makes sense (unless this is a troll) is that you're getting that false message that you've been banned, which have happened to several members before. That's the only way I can make sense of it, since you're saying you get it everyday, which means you're able to log in again at some point. I don't know why you'd be getting it everyday though. In case an admin might not see this, you may want to PM one. They're the ones with the red usernames.
Oh wait - I just thought of another possibility. You may not be aware that we're not allowed to use proxies or VPNs, and I remember an admin saying that proxies are automatically banned once detected. Though, that would mean you have several alts that you keep logging back into using a proxy lol. If that's the case, you may want to stop that.
Then there's the possibility that you're logging into your alts even though your main account has been IP banned.
