So again, this game isn't extremely bad, but there is a lot of unneeded arguing happening here. What you are doing in this game is adding to the negativity that's already there and making the situation worse, which is simply not needed
MattiasNeeson: STOP
MattiasNeeson: PINGING ME
MattiasNeeson: AND HELP ME
MattiasNeeson: YOU ARE THE SUPPORT NOT THE DANGER ALERTER
MattiasNeeson: don't talk troll
MattiasNeeson: makes me cringe
MattiasNeeson: try so hard just to get these kind of people
These are just a few of the comments that are really unnecessary and just serve to make the situation worse. Instead of saying in all caps "STOP PINGING ME AND HELP ME," you could try and say "could you please stop pinging me." Also, calling another player a troll is never going to help. If they are a troll, calling them one won't make them stop because they realize they are making you angry. If they aren't a troll, accusing them of being one is simply going to make them angry and possibly retaliate back by either arguing back at you or possibly by actually trolling. Either way, calling someone a troll will not help.
Now, you still haven't provided all of the games you received, though you do admit to being a dick in the second game. So, in game 1 there's slight arguing, game 2 you admit to being a dick, and game 3 there's a decent amount of negativity. Overall, each game may not be worthy of a punishment on their own, but add it all together and you get someone who is showing negative behavior across multiple games, which generally does lead to a punishment.
