Dont open emergency shutters if you dont know what is on the other side, they are everywhere. They also almost always go down, so there are not really many reasons to bolt doors except deny access. At least I cant think of much from the top of my head
People don't care, they already know that, it's not working
Not a problem anymore since malf is a voted gamemode and not in the secret rotation
This is an idea that was brought up in the past, and I still think that's pretty good. Camera tracking is way worse than bolting doors imo
