I use the in game taunts if they have them all tiem time!
They are a valid tactic, as more often then not people will forget all about the objective just to find you and kill you. If i can lead 3 peeps around on a wild goose chase simply by taunting them, then that's 3 less people out there ruining my temas chance at victory.
Just gotta be careful. It's easy to say it's just a game and people need to relax, but that anger can rise up rather fast. I try to watch for it, and when I catch myself getting pretty riled up, know that I best take a break for a bit.
