LOL at that link. The pic and comments are priceless. There’s some discussion about whether it’s legal to publicly shame someone in the way that company did. The internet is so relatively young there probably haven’t been any court cases about this matter, but I’m going to side with the people who say that if it’s on the internet and not copyrighted, it’s public domain.
Another poster (in the link) said, “That’s why I made my Facebook page ‘private.'” My kid (age 19, and, of course, legally an adult) has a Facebook page without the kid’s real name but I easily found it using the nickname the kid uses for hotmail. Nosy parent? Yep. But no matter how old they are, you never stop worrying about them.
