True - but I feel that, in general, people are a bit to skittish when it comes to this stuff. If you have social media, there is a good chance some random person could just find out who you are anyway by simply browsing the web.
And then what about that thing called going outside? Tons of people can see (and snap a photo of, if they want) your face. Yeah, it could be considered personal information, but it's about the furthest thing from it in that category.

Actually, I could post pictures of like half of the people here in Hawken, yes I am some kind of stalker, heheeeee. But it is fairly easy if you know how :P
Still, as I have no right to do that, it is up to them, haha.
However, I like this thread, shows which person I am annoying or making go rage. ;D
