Flagging because you don't like a subject is like the kid taking his ball home because the rest of the kids won't let him win.

If there's to be a valuable system of not rewarding plagiarism, spam and abuse, then rather than consulting @steemcleaners, maybe another way has to be found?

One flag only. Once a flag has been posted then the blog post in question is frozen (the time is paused to prevent abuse that way too).A while ago, I suggested the act of flagging a post should cost Steem. The Steem is taken from the flagger and put into an escrow account. When the flag is reviewed by an authority (like @steemcleaners) and the flag upheld, then the whole post is deleted or greyed-out (whatever) and the Steem returned (with interest/added reward if necessary). If the flag is deemed negotiable (editing by the author of the post will make it right) then the Steem is also returned. If it's an abusive flag then the Steem is forfeit.

Flag-wars will be stopped, spam-flagging (which prompted my initial idea a while ago) would stop quickly too.
