My concern now, after having five individuals walk into my home, at different times, and get right into my face is, how in the world is a person supposed to feel safe and comfortable if they want to spend an evening at home with their significant other? Anybody can just come in. Sure, if I notice them, I can eject or eject/ban, but always having to be on the lookout for these kinds of people just isn't cool.
In rl people can't just walk into your home uninvited. I think banlines are horrible, but some way of keeping people out when you're home would be great.
