I'm not sure it it's LJ or what, but the community we_are_lost had a lot of obnoxious people in it, as well. I finally left. Now that I'm so involved in www.thefuselage.com, I don't need LJ communities for LOST. You should check it out. Sure you have some obnoxious people, but there are a lot of great people there, as well. It's a bit overwhelming at first, but it's a great site. Come on over!
