Sounds like you gave a reason for Flags - Plagiarism
So how does a flag work that only addresses plagiarism? Maybe a punishment to the person that used the flag future when no plagiarism is found? ok, so what is that punishment, because a bot could care less about losing rep or rewards.
Tough Questions when it comes to flags, especially considering if you have $5,000 to invest you could create what 10,000 or 20,000 bots maybe more. Maybe I'm talking out of my butt here a bit. A good way to look at anything in my opinion is "ok i want this power" now imagine if your worst enemy gets the power instead. Still want that power? Or better if no one has it?
