The only thing is that in some cases someone will not be banned for a case of plagiarism that is considered minor, that was a long time ago and that was only one time.
Then there is
this case where user plagiarized multiple times, not long time ago and still no punishment whatsoever.
Well, and also suchmoon has repeatedly complained about not handling plagiarism reports in the WO thread:
Remove "Report to moderator" from Wall ObserverAs far as I know, plagiarism is not allowed. If it were, the unofficial rule would have to be changed and it would have to be announced in Meta.
The bad thing is that no one explains why these cases are not handled and leave us all in doubt.
