I know there are plenty of them. Weather you don't like the way he or she looks. Maybe they post annoying questions. Maybe they just post annoying opinions. Do you feel that way about some users on here? Why?
I usually find users whom don't respond to an opinion nor select an MHO. But all are anymmous.
People who ask perv questions (what underwear are you wearing, etc) annoy me a lot, but they're usually anons so I wouldn't know who it is. I don't think I've ever seen anyone who posts annoying opinions anyway. There was a guy once who used to write very sexist stuff all the time but it was a long time ago. I hope I'm not annoying either :o
