Nobody seems to read (including you kid), never mind read what they click. You and you alone allow all the nefarious crap on FB. You are also responsible for your very own security and privacy settings. Imagine that. But the whiners will try and find blame elsewhere or justify their little rage.
The tag/brag and share is similar to the way some idiots will fast-click through EULA's and opt-out boxes then cry because they have some spyware toolbar or search engine on their rig. Too bad.
Over the course of 4 or 5 years with a Facebook account they've reset my privacy settings a couple of times, as well as reset notifications. I got tired of changing notification settings back to NONE so finally just established a baloney email account for facebook .. an email account I rarely check because its only full of facebook notifications I've repeatedly requested not to have.
Heheh...My own test was to open another facebook account under a fake name and tried to find me.... with no luck......I thought since you were more into that technology stuff...???
