I think the pemanent ban for plagiarists is very hard to remove unless you can make a good case on why the forum needs you be back again. Waiting for the ban to remove is not enough to remove this punishment since it’s a permanent ban.
When (I think in 2018) there was a mass ban of users due to plagiarism, some of those who received a permanent ban still got a second chance with a signature ban for a certain period. And we are not talking about a few users, but about several dozen users who got a second chance, while some others never got it - but each case is a case for itself, so I guess some are recognized as worth saving, some others are not.
I have no doubt that the OP really wants to get his account back and that he has been persisting in this for a long time, but in the previous post I wrote that things are not as simple as they seem. In order to end this story once and for all, I would recommend (and I think I already did once before) that the admins review the IP logs of all accounts that are possibly connected to the OP and determine whether there is a connection between all those accounts.
If such a connection exists and if only one of those accounts is banned, then this whole story no longer makes sense.
