some player (vansmoot) told me that HSGG got banned.
is this true?

its true man, only 3 days though

also, vansmoot told me he is HSGG.
is this true?

Never heard of vanmot but i have been told that hotshot gg has multiple accounts

Saint Vicious also got banned. Apparently he was trolling someone for a very long time over his stream. Don't know why Hot Shot got banned though, but probably something along the lines of language or trolling. His ban hasn't made as big of a commotion as SV's ban though. I know many people have different opinions on this matter, but I think its great that Riot treats everyone equally and isn't afraid to do so. Gj Riot

Wait yes I have been told that hotshotgg does have an account named vansmoot not vanmot
