This in from @enforcer48 In a response I made to one of his post about @quarantine, that also help combat Phishing, and Flag harassment:

I would also like to mention @freezepeach as well.
@neutralizer and @randohealer also helps out in that department.

So take a glance at them and see if they can help with any flagging problems you encounter. Remember no matter how much you would dearly love to retaliate, some of those accounts will not help in a flag war, so restain your urge, report the actions, and let those with enough power to deal with it deal with it.
