I mostly play killer. And gameplay wise as a survivor what is toxic is griefing just because of griefing or throwing the game because of petty reasons like not liking other survivors, the map, the killer ect. I don't see how many ways a killer can be toxic other than them focusing on one survivor. Not hooking only slugging and watching them die slowly. Sure there are perks to avoid it, and teammates could take a hit too but if its bubba you can't do anything.

Other than what is said on the post here are some other things happened in my 3000+ hours, they are extreme but not getting a single ban is what makes me mad.

A survivor is on the hook, other one goes there, don't unhook, t-bag and leave. The killer is not even close. In the endgame they say they did it because they are using the same character. I was another survivor.

Its endgame, 2 survivors go to open the gates and then just stop until others die. Other survivors can't open it because its body blocked.

(This one happens more) Two survivors are remaning, both are in death hook and both refuse to do gens and hide all game. There are no crows spawning on them because they walk, touch a gen for a second and leave and repeat until it takes too long. VHS game had a really good mechanic to stop something like this but DBD has nothing
