But it's stressful growing an account from scratch to a high profiled account only to get banned permanently without any form of future consideration.
This is a reality that everyone has to accept, because plagiarism is a form of virtual theft, and if you steal something in real life and get caught you have to bear the consequences. However, I believe that everyone who made such a mistake, and was a valuable member of the forum, got a second chance, the only difference is that some waited for a second chance for 2 days, and some for almost 2 years.
I've seen maybe two cases of a permaban being overturned in all my years here.
I remember there were a lot more than 2 cases, especially considering that some got a perma-ban which was then changed to a signature ban (see a post from @DdmrDdmr). I well remember the long-running case of @RegulusHr being unbanned, and also the case of @bill gator who claimed he didn’t know about the plagiarized posts because he bought an account from someone, but also @Aveatrex, @ChiNgadOr, @tvplus006, and some other members who were given a second chance.
This is what bothers me too, unequal criteria in similar cases.
I agree that plagiarism is a very serious offense and should be punished and I also agree that deserving forum members, with a high reputation and the support of the forum community, should be given a new chance.
What I don't understand is why some cases of permaban are resolved in 2 days and some are resolved in 2 years, as was the case with RegulusHr.
In the case of RegulusHr, the whole local community gave him their support, and that support didn't stop for a full 2 years, and that was the main reason that the permaban for Regulushr was permanently removed.
To answer the question of the OP, permaban can be reconsidered, but only in the case of a deserving and distinguished member of the forum, who has the great support of the forum community.
