It's not that the picture is being posted that make the site invasive, it's the fact that anyone can go and look through those pictures, there is no lock or limit and the few that they advertise can easily be bypassed. Look at it this way, people have been denied jobs because of something a company found on facebook about said person... It's not always that person's fault for posting it either. The fact that the site promotes stalker like behavior alone should be enough to consider it invasive.
I've heard about companies using Facebook and similar sites to check out applicants and then turning out applicants because of what they saw online. The thing is, if you don't want stuff to be used against you, then don't do it. If I get drunk at a party and run around naked, someone could record it and put it online, and that could keep me from getting a job, but someone could also just tell the company about my doing that, and I could not get the job. The sites themselves are not invasive. Only people are to blame.
Besides, the sites don't promote stalker-like behavior. That's people, again. Each person can post as much or as little as they want. Some people list every job they've worked at and every school they've attended, but it's not mandatory. It is entirely possible to join a social-networking site and have just three friends and no drama or bullshit. You and your friends don't even have to talk about anything, just use the site to communicate without email or calling each other. Yeah, people from real life can find you, but you could, you know, lie and give a fake name and a fake location and a fake everything else and only give the link to your profile to trustworthy friends. Now, how is that invasive?
