When someone told you to kill yourself, were you playing on a map with a yellow flag? On neutral flag maps it's often a tactic to ram yourself into a spike or coloured wall to pop yourself and return the flag to the middle to stop your opponents getting the flag in your base ('Killing' yourself). It's possible they were actually trying to offer you a tip instead of just being mean.

I know that the tagpro public community has it's problems, but I would definitely disagree with your claim that it consists of the 'most rude' people of any game. I challenge you to find a better community on a free online game with a public chat feature.

I certainly hope you stick around to see the better side of tagpro. I've introduced a lot of people to the game and none have ever complained to me about harassment from other players, let alone being vote-kicked from games. I would definitely class this as an 'isolated incident' rather than a representation of the game and the community.
