I was playing a 3+2 blitz game and I found this opponent: @DKingIsDead.
I was shocked to see those numbers.. and this was the game.

Stockfish said that he played like a 950, and I played like a 1750.
Looks like next time I shouldn't be rating my opponent's skill based on his followers and views (I'm still trash at blitz btw but aiming for improvement).
