you have to be reported MULTIPLE times, your heimer game alone (not even taking the score into account) is definitely ban worthy, you're negative towards your team and seem like someone i'd rather not play with.
your other games aren't to bad, but you definitely need to work on uhm.. being a better person online if that makes sense
you've been banned multiple times before this, and you need an EXTREMELY high frequency of receiving reports to even be sent to the tribunal. If you've been banned before and are on your two week ban, this is pretty much your last chance to improve on being a better person in the game before you lose your account.
the games it selects for the tribunal are completely random, you were reported in MANY more games, you do deserve your ban, and hopefully you'll actually learn from it (although you probably won't since you've been banned multiple times)
