You have to ask people of the community here, what they have given back, and not what they gathered as pride, earnings or anything of that sorts; Do people here feel to be in the right place? Or are they constrained by their duty bound to their signature, boredom, and escaping reality? What have you learned? What keeps you here, on this forum?
If you have Plagiarised more than once, probably your chance to get the account back is a no go area. Probably even the apeal email link that's been attached to the Waring message I don't know if it does work.
