Why does this even have to be a request?

Big yes, but there’s an issue with delayed bans. When you lose Elo and then queue against lower-rated opponents, you might win a lot and regain some Elo naturally. If Elo is later given back because of the ban, the Elo you get back might have a different value. You see what I mean?

This is exactly how chess.com handles it, automatic Elo refunds. Emailing is ridiculous.

To which email should I send the request?

It's a shame that this is not the case yet. We have lost so many elo points on cheaters... What are the devs thinking ?

i tot it did happen automatically
