Besides having to let this account in means anybody who has waited a long time can get a second opinion as this will set precedent for everyone banned to get second opinion and get unbanned.
I think that here we should focus on what is the real problem, and that is the very justified suspicion that the BTT account in question is just one of a series of alt accounts that the OP owns or has owned, some of which have been permanently banned. Therefore, this is not about plagiarism exclusively, but the
"problem" is much more layered, and if for 4 years no one felt that there was even the slightest doubt that the OP should get a second chance, then it will not happen in the next 4 years either.
Each case is a story in itself, and 99% of those who received a perma ban have long since forgotten about it and will not look for another chance.
