You're wrong. A downvote is a downvote and my downvote is the same as yours and the same as any account's. The downvote doesn't have any parameters to it as to why it was cast. You know this. Why would you assume that a downvote cast is only cast for plagiarism? I don't see any comments on any posts that are non-plagiarism. And you yourself know that actual plagiarism is illegal. This is a pointless argument.
