if you're saying that it's really rare to find cheaters in valorant, they you're probably stuck at silver or gold. there is 100 pages of cheat in elitepvpers, and hundreds of threads about how to make cheat in unknowncheats. yes, riot is banning those people if they're rage playing or gets a lot of reports, but that's not the point.
this guy was pro player, played with cheat for a year. players in tournament keep claimed that this guy was cheating, riot controlled vanguard's logs and said he's not cheating :) after couple of sussy videos, he got banned.
so in cs: you can rage cheat without ban
in valorant: you can legit cheat without ban
in faceit: you can't cheat easily.
also, the cheater detected message is so funny. because vanguard is not detecting the cheater instantly, it's called ban wave or delayed ban. so the cheater probably keep cheating for a month, vanguard or riot is banning him now :)
no game is cheat free, valorant has cheater issue in diamond elo+, if you check leaderboard, each day someone will demote to end of the list (that's how they're banning, setting his lp to 0 and ban) but riot put a rootkit to our computers in order to make the game "CHEAT-FREE" but still a lot of cheats :)
don't you believe me? go try to buy second hand immortal account (NOT RECOMMENDING, IT'S TOTALLY ILLEGAL) it'll probably get delayed ban end of the day.
also, forgot to mention. this nisaY guy was EU #1 in leaderboard for a season. :)
