Do you remember the account you bought your account from? Do you have the wallet file you used to pay for it? If so, can you post the TXID?

My personal opinion is that you should not be punished for buying your account 4 years ago via your trust score. I am willing to debate anyone who disagrees with this, and anyone who is unwilling to defend the trust ratings they leave has no business anywhere near DT.

I believe you should be unbanned if you really bought your account, and there was no plagiarism after you bought it. Unfortunately, the prior owner plagiarized a lot, and this person probably should have all their accounts permabanned. Also, unfortunately, it takes a lot of effort on the part of the administration to verify the claim your account was sold, and I don't know for sure either of the admins will be able to take the time to verify your account was actually sold.
