Lol dude you're level 18 what do you expect. People think they're good because they have ridiculous scores, but ELO isn't determined by scores; it's determined by consistency.
Additionally, you're receiving negative feedback because you're toxic. Lol. You inted in multiple games, and admitted to it. Your teammates being bad has nothing to do with player behavior, but your toxicity does.
Thirdly, you've been referring to people as though you're older than them, which has conceited connotation. For all you know, somebody here could be fifty and you could be thirty. It's rude to refer to somebody by their age like that, when you don't even know it.
Calling somebody a "numskull" (which, by the way, is spelled "numbskull") is also rude, and you've consistently expressed immaturity on this topic.
We don't punish players for losing a match. We punish them for flaming and generally being rude and expressing toxic behavior.
"As an adult you have to accept consequences basis on your actions and admit to certain misdeeds."
I'm afraid to break it to you, but being an adult has nothing to do with maturity, despite the social connotations it has. Maturity means both acknowledging your "misdeeds" and acting accordingly to make sure it doesn't happen again.
Finally, you appear to be smurfing. If I may to inquire as to your actual account and rank?
Edit: Also, I just noticed-- didn't you say you were permanently uninstalling about... three months ago?
