I wouldnt say "Cold", but there are definately some pesudo-trolls around here that think the things they say are cute, and that everyone praises them for their one-liners.
Also, alot of the things you see are kind of like inside jokes that could come off as sarcastic statements. Some of these 70+ levelers play together everyday, and things are said that are only found funny by those that know the poster. I know if you went into my LS message board right now you would think we were all nuts because of the stuff that goes on in there, but nobody would find any of it humorous if you didnt know us.
Third, the ass-clowns that are "cold" are also the ones with 1000+ posts you notice. For every Rones and Skaw out there, who have quality information in every post, theres a Decidence or Ithenas or Westyle that post one liners constantly to jerk people around. (Not saying that i dont like those 3, nor do i have anything against them, theyre just the first three that pop into my head. If i had a dollar for every post i saw from Decidence that started off with "lolsomething", id be rich...but i find them amusing, id imagine some others dont. I.E. the OP of this thread ><)
