@NoorulHuda2 , you gotta study that case and see if it is related to your case.
Nothing much to study tbh, each case is evaluated separately and since that unbanning didn't end up well I don't think it will help him much.
I think exactly the same as you. And I am surprised by this lenient policy with those who break the rules.
Forum policy went from being too strict and banning good members for having one plagiarized sentence or two, to being too lenient and not doing anything for obvious plagiarism and I think some middle ground should be found. For example, giving more signature bans, preferably for longer period of time (not saying that OP deserves the 2nd chance btw).
