Op, I want to let you understand that there is no rigid rule about plagiarism. I always tell other members of this forum that there is no rigid rule here. This is a forum of liberty just like Bitcoin.
Can you tell me how many rules do you think are not rigid out of the 33 rules
listed here? I don't want you to underestimate the rules because I believe plagiarism will be banned on this forum without even needing a warning. It's great if the OP gets a warning and fixes the error, but what if no one else is willing to warn him and just report his plagiarism to a moderator to get banned?
