How and i supposed to come back in 2013?
Just come back in January of 2013 and appeal again. We are almost never so upset at people to never welcome them again, if they try to apologize. You just need a cooldown and a meeting with Tell-The-Truth Foundation.
Last thing.. Will i get banned if i buy a new acc?
Waste of money. We always find out, eventually… and using alts to avoid bans is forbidden.
