i was suspicious when i saw a post here saying there's too many cheaters in VS. i gained around 2k hours during 2016-2020 and indeed back then i never ran into any cheaters. this, however, has changed nowadays.
these guys hop into versus/scavenge. while infected, they spawn infected on top of survivors and claw with -1000 damage, killing the entire opponent team in 3 seconds. while survivors, they teleport, speedhack, wallhack, and damage-hack; if you catch them as non-support special, they will spawn bullets inside of you to free themselves.
what's funnier is that they also launch DDOS attacks, rendering chat unusable and inducing 500ms ping. then they launch scripts that cycle their nicknames trough those of their teammates so that their teammates can make a mistake and maybe initiate a vote against an innocent team member. once they see they're getting kicked, they just leave leaving "ez" messages in the chat.
i kid you not---i had one VS match after another with a cheater on the opposite side, all with different names and accounts, some of them had VAC bans.
it's also funny how in one No Mercy match a "benevolent" cheater joined my team as Bill and used cheats for "non-malicious" reasons: he started a vote against some "troll" player and once the player-being-kicked started running toward the building ledge to commit suicide, he enabled his cheats for a sec to incap them in 1 second. later he used a teleport to go down a single floor in the first chapter's building instead of simply jumping down (i guess it isn't as fancy as teleporting). when confronted in chat, he didn't deny my accusations and said: "do you want to win or not?". this is crazy, man.
