The real cause of bad solo queue survivor behavior
It's queue times.
When survivor queues are instant, there is absolutely nothing stopping them from killing themselves on hook. They can use this to get out of a match early and immediately go to another, or have the luxury of shopping around for 3000+ hour teammates or 4 medkit/BNP toolbox teams. Generally survivors in this game state are unhappy, BUT have the ability to quickly cycle through matches to find one they like, enabling and even encouraging their bad behavior since they technically did not disconnect.
When killer queues are instant, as pre-6.1.0, it means the role is largely miserable. Yes, they get to shop around as well for no-item no-obvious-SWF lobbies, but this was not enough. Generally killers in such a state of the game are also unhappy, but do NOT have the survivors' ability to quickly cycle through matches. A killer game that goes bad enough to cause them to give up is often a 10+ minute wait for the killer if they don't want to eat a DC penalty, so they'll often begrudgingly play it out anyway.
The difference is survivors have no reason NOT to throw the instant things aren't looking up for them, as they don't get penalized outside of having to wait another 5 seconds in queue. If they had to wait 5+ minutes, as was often the case pre-6.1.0, then they'd play it out.
The solution is to add a forced timer to queueing after intentionally dying on hook. War Thunder does something similar, in that if you eject from your aircraft/crash into the ground without being damaged by an enemy you cannot queue with that crew for 8 minutes minus however long you were in the match. DBD could implement this fairly easily - the game already has a flag to cause an immediate sacrifice after 2 ignored struggle skillchecks, just have that event set another flag that prevents the survivor from queueing for a set period of time (7+ minutes) to discourage this behavior.

I play killer mainly, but I do play solo q occasionally. You bet I'm going to play whatever side needs more players, you kidding me? Gimme those sweet, sweet Bloodpoints bby!
