Looks like you are in a pretty tight situation here, let me shape it up for you here Decoded, one of your alt account got banned so your main account, Decoded, is also affected from the ban evasion rule. Now your main account being hacked will obviously be subject to recovery. So I don't know which will go first the appeal for the alt account before the recovery of the main account or vice versa. I don't even know if an appeal for an alt account is even possible especially the ones we always see being appealed here are main or only accounts of the user.
It's not that my main count has been banned, they state that my information provided is "insufficient" and they would rather "lock my account than have it land in the wrong hands".
They say their decision is final, and I won't be getting my account back. Is anyone able to do something about this? I used this site often and I'm quite worried. Like, if they gave me the reason that it was for evasion I would at least understand because it made sense. But why is my information insufficient? They didn't even ask me to stake a btc address or anything.
