There shouldn't be any measures to prevent killers from camping/tunneling
It's a feature of the game and most killers, especially C/D tier, use it to attempt to win matches. For certain killers it is even a 'cool strategy' as directly stated by a developer regarding Bubba.
Yes it's annoying especially several soloq games in a row but is an anti-camp/tunnel provision really a priority? Yes it is annoying - and after? Be angry for a short time - click continue - and play your next match.
Nothing happened.
I even found a super niche technique to prevent it from ever bothering you; just don't get bothered by it.
Just as it is the killer's fault if they let teabagging or flashlight macros get to them, as the developers clearly say, it is your fault if you let camping get to you. By the way, unfortunately with regard to Bubba's mask the developers did not have the courage of their convictions (if they were fully consistent, they would've told the people who were sent racist messages that slurs are just words, and to get over it).

Agreeable, killers should have incentive to leave the hook or go for another survivor instead of the recently unhooked one.
