I find myself often annoyed with the level of lewd in the community. 
It annoys me when I say something and get attacked by several people trying to turn my comment into sexual innuendo. It annoys me when I go afk and come back and someone is doing the hilarious totally original "joke" where they're humping the afk guy. It annoys me when people are hanging out in highly sexual or outright naked avatars at the meetups. 

I would say lewders that have no off button are my biggest pet peeve right now. It was my hope that vrlg would give them some containment and release so they could keep to themselves a bit, but so far vrlg has only served to make it worse.
