I'm sorry to say that no amount of appeal will get your account back to you. I suggest that you since learn from your mistakes then just create a fresh account and just be mindful of not plagiarising again.
Creating a fresh account is also not acceptable by the forum, this very account is only allowed to make this single thread,as any other thread/comment outside of it will also result in a ban..
A ban to an account is also a ban to the user, so operating on this forum with any other account will be tagged as ban evasion and would also get banned if caught..
But obviously you'll just fall back to one of your alts and creep quietly back into the forum..
We all know about that
Try not to plagiarise again when you do that
