Just for your information, there is a "flag" button on the "X points by Y" line, which can be used to mark spam messages. (Or at least there is if you have over some amount of karma.)
That's way too funny. I saw this a while back and thought 'flag' was to bookmark the post as 'important'.... so naturally was 'flagging' some of pgs' posts. I'm glad it didn't end up marking his posts as spam!
