Nobody really knows for sure why these trolls troll here constantly.  I think Icetroll works for the government, or certainly is paid by someone like the government, ariel is too dumb, but could be getting paid for his/wanna be her posts, and Dalanar or however it's spelled, is a poor mislead sap that has hung by their coat tails.  There are so many more, and they're probably sock puppets of only a few people.
