@curatorhulk was claimed to have been begun for this purpose. Unfortunately, I've seen no activity from that account of late. @freezepeach does act to counter abusive flags. Some other accounts might do these things too, but I'm not familiar with them because every problem flagging I've sought to rectify has been solved by @freezepeach.

More folks delegating to @freezepeach, and more initiatives begun for this purpose would help.
