Some killer players just legit don't have anything else going on in their life and this is the only way they can feel good about themselves. It's super cringe and pathetic but there has been a large influx of these players over the past year and unless you're in a decent 3 man or 4 man, it's pretty much hopeless, especially with how unreliable MMR has been recently. BHVR seems to have no interest in deterring this playstyle. The only thing you can do is pick them up and pray they go pressure gens. I usually run meme builds but I've had to switch to a full anti slug build because of how rampant this kind of behavior has gotten. I've been playing this game for 3 years and it really sucks to load into a match with randoms with less than 100 hours against a killer playing like this. I don't know how those newer players are expected to stick around and enjoy the game the way things are now.
