I have been banned for what I consider unfair reasons. I had no idea that getting your account hacked was common enough to be a problem so my account was not secured  so here I am. I lost access to my previous account, which was apparently used for multihack. im new to this game so I really don't know much about hacks or protecting my player.so if plz can unban me I will be more careful to watch my player

Claim your account first.

We do not unban hacked accounts. Read why here. Let this be a good lesson for you to secure all your accounts with at least 2FA where it is possible.
