For about 2 years. I started playing I believe during season 2's snowdown showdown (definitely since season 2 at least) and have never recieved a warning or a ban. I try my best to treat others with respect as well as treat them the way I would like to be treated. I also don't curse in chat regardless of the game I play, as that I feel is just being very immature as there are plenty of other non-curse words that you can use to get your point across.
I'm certain that I've been reported before for having bad games or being "overly-sensitive", but like with wizard101 and pirate101, I know that the false reports will be counted against those false reporters and not me (and since I play with lv.30's even though I'm currently only lv.26, I often find myself reporting people after some games).
I like to participate in the tribunal not because I know I'm gonna get a reward (though technically the reward is clearing the community of foul-mouthed, immature players), but to help clear the community of toxic players.
To those of you reading this, if you just treat others the way that you want to be treated, then you'll be fine and chances are you won't be reported and/or wind up before the tribunal, it's just that simple.
Thank you for your time.
