[2021] I have one question... how to report hacker publicly if you can no longer see the profile ? Should I offer him friendship ? like: nice hacker, can I be your friend ? now I play since S1 2019 and this is getting more and more ridiculous.

Heya! While a UID helps us report these types of players, we can still report cheaters with just their nicknames. We are investigating this one to see what we can do.
