If you know how to game the system, you can ruin as many games as you want and never get punished...
...but if you retaliate, with no concern for tricking the system or trying to be subversive, you get the stick.
For example, if I wanted to, I could run it down, build a legit build, and say things like "oh man im sorry I didn't know they did so much damage" "oh woops didn't realize i was in tower range" "oh my bad guys" "oh gee golly willakers I sure am bad at this game HAHAHA" and I would get away with it indefinitely, 100% guaranteed.
If, on the other hand, I'm another player in that game, and I say "bro fuck you why are you trolling you piece of crap?" and literally NOTHING ELSE THE ENTIRE GAME? BAM punished.
A system that punishes the least common denominator among toxic players, many of whom are JUSTIFIED in venting their frustrations, and ignores or even rewards those who have figured out how to abuse it. It's working fine guys, don't worry about it! They are doing everything in their power to combat toxicity in the game, stop giving them such a hard time!
