give me suggestion for this 
Find a different forum? You clearly were banned for a legitimate reason.
it hurts buddy
, thanks for your suggestion.so i get banned because forgot to mention my another 14 alts acc? so i have no chance to fix this case?Having alts isn't against forum rule, just wait until the ban period is over and make sure you won't broke the rule again.
BTW, what did you do with these 15 accounts? Farming signature campaign?
