so people don't make flagging an act of retaliation.

Yeah, that's the worst kind of flagging and I really hate seeing that happen... A user with 1000 sp flagged a big user once and he went and flagged all the active posts of that minnow with like 100k sp..

What can you do. Right now there are not a lot of high SP users but with time and more eyes I'm sure things will get countered on a more fair basis in general and abusive flaggers will have a harder time while ruining their reputation.
