-In my 3 years of playing the game, I've encountered 6 cheaters;
-All of them got banned (I think, I know for sure 4 of them did), 3 of them mid match;
-Although 6 is a really low number (astonishing low to be completely fair), out of the 6 cheaters, 4 of those were in the span of the last 7/8 months;
-For me, they "come in pairs", and by that I mean that, every single time I would get a cheater, another one would appear in the same day. Either the game right after or a few in between.
To sum it up, Valorant does a really good job at preventing, detecting and stopping cheaters from becoming an actual problem and is the least of my problems regarding the game.
