The example you gave is not related to what the OP is asking, that one was farming against a user for plagiarism, what he is asking is a different thing.
I understood clearing that's why I said if he wasn't asking exclusively based on his example i.e asking a general question if framed cases have been solved before that's why I provided that topic of a scammer framing an innocent users, to let him understand that framed cases can be resolved. then later went on to give my opinion to the topic based on the example he gave. Read my OP you'll understand my reply.
