LJ has added new "flag post and/or journal buttons as offensive" buttons. The more flags something gets, apparantly the more likely LJ Abuse is to take an action.

bad, bad man who is already finding ways to abuse this for the sake of amusement. Of course, others report that if you plant too many "false" flags LJ Abuse will just mark you as someone to ignore flags from. Not that I have any idea how they define "false". But lack of clear definitions is what makes LJ Abuse so much fun!
