Well colour me shocked
Facebook doing what it wants without reguard to users rights etc I would never have expected that.
One of the many reasons I never use it.
You sign up - you opt-in. Don't want the crap don't use it.
Want to use it then at least get to know what you're agreeing to. That's what makes sense, not disavowing your personal responsibility and blaming someone else because you're so caught up in the social media frenzy you can't think for yourself.
Woah, paranoid or what. Someone posted a picture of you and now you're being stalked by facebook. Do you get targetted advertising, do they tag your photo to what you like or have ordered online. No, I didn't thinkk so. I'd suggest you un-friend in real life whoever posted the picture.
Doesn't really help. If people who know you have a Facebook account, then you'll already have a hidden shadow profile populated with most of your personal and contact data. That seems like more of a problem - there's no mechanism for checking this, correcting it or deleting it.
And it will get updated with every web page you view that has a Facebook widget.
