FaceBook still letting us down

I connected to some random site today and was annoyed and alarmed to see my basic FaceBook details (photo and name) appearing on the site. I had no prior connection to the site and didn't wish one.

In the past, it has been reasonably simple to prevent this type of thing, but because its a way for bussiness to make money Microsoft and other have been making it "Harder and Harder" to keep yourself "private" (or, as they will sell it, easier and easier to share).

I never wanted to really be a part of FaceBook but I have friends that did and I am there friend and joined for there sakes. I think I should leave for mine.
