Yes, one just doesn't see that sort of thing on oswho sites; I can see where you'd find it upsetting.
But I can't help but ask: Who's obsessed -- a group of fans that have a bit of fun over the misfortunes of their in-state rival (though, given the head-to-head record between the two programs, it's hard to really think of it as a legitimate rivalry) or the oswho fan who, day after day, visits this site, his eyes peeled for any negative word posted about his orange-clad heroes?
I'd say the opposing fan who can't stay away from a rival board takes the prize.
