Let's think critically for a moment: Is it more likely that a 14 year old girl liked the AT&T page in all her days of using Facebook and forgot or that this is normal for Facebook ads that would potentially open them up for a huge lawsuit, after all this is basically libel.
Also check out this author's about section. He's a Google+ fanboy (Google+ is pretty nice, nothing wrong with liking it) and hardly a biased source.
Articles like this and its spread of misinformation highlight the inherent dangers of how easy the Internet has made it for random, misinformed people to get massive reach and it seems that even our "enlightened" community has fallen for it.
I am so disappointed.
