Not me! On Facebook it even names your friends who have liked this or that. I don't even believe that! Unless I actually speak to that person directly and get confirmation from them, I'd never click on anything like that.
My brother works in IT tech and he has taught me not to click on things like that. Even here at work, I'm scared to do updates sometimes. I always double check with the IT person first.

But yes, there MUST be people that do click them. Otherwise what would be the point of putting them there?
