Why the heck would they enter the BB house in the first place for any other reason than so that people can look at them? The are a typical example of narcissistic people who want to be famous for nothing other than being famous, so yes, I would say they spend a great deal of their time thinking 'who's looking at me'.
I'm not saying they don't deserve respect, but talentless people who shout "look at me! Look at me!" can't really complain when people do.
There have been well over a hundred housemates now. I would certainly not tar them all with the same brush. Some have quietly got back on with their lives. Still, they were once in the BB housemate so they don't deserve privacy now.
