those are the alert buttons that people are pushing. thank god Webmaster made it so the button could only be pushed once. before, i would get an email for every time someone pushed it. h = bad message, a = good message. people do hit the wrong button by mistake, too. i say give that post an R rating.
not always a troll. fer instance, I'm on hubby's laptop right now, this thing is soooo sensitive that if the cursor rests for a bit, it'll click through to that link. I know that I have "alerted" unintentionally.
