You're right...it is possible. However....the honest truth is the number of irrational LOF's far outweigh the kinds that you just mentioned. Or at least the number of times they post/troll on all the threads at least.
There are trolls of all types. Use the ignore feature. Don't feed the trolls. They feed off anger, hate and irrational discussions. They will wither and die... They will go to other forums and seek attention elsewhere if we all ignore them. Don't take the bait.
