You use your hard work earning for it. And you underperform in your games, people know that. They will report you and eventually you will be back to your real rank.
Why you do that? C’mon I know you guys are lurking here. Tell me the answer I’m just curious.
They’re not in touch with reality which is why they’ll often be blatantly playing worse than everyone else in the game and also trying to flame and blame other people at the same time.
Their brains aren’t capable of accepting what their actual skill level is so they buy accounts to play in their “real mmr” that they deserve and if anything goes wrong in those games (usually their fault because they don’t belong there) they blame.
