The selective quoting of the snippet does sensationalise the actual content of the blog post. At the end of the day, you dictate what information about yourself is revealed online, and control what people can find out about you, it's your responsibility in that regard.
That doesn't justify the actions of some people (which at no point did the article attempt to do) who use that information for abuse, but it does ask a very valid question of "What did you expect?" While we'd love to put our fingers in our ears, and close our eyes and "la la la" at the top of our voices, the truth is the internet is a barren waste of utterly degenerate shit and pond scum and those people exist to merely piss on your lawn, because they can.
While people would rather wish they didn't exist, and that we could talk freely on the internet without repercussion, the blog serves as a bleak reminder that they do, and that we all must tread softly and carry a big gun. Yes it sucks, but the first step to overcoming a problem is admitting it exists.
Pity that a lot of people that believe people should be free to say what they like about themselves without being afraid of trolls are often the same people who kick up a fuss when governments encourage the police to prosecute over internet trolling.
Furthermore, any GM has to work to company guidelines, rules and restrictions. Telling someone they didn't do their job is a very strange accusation when in fact what you expected them to do instead would be them operating outside of their parameters.
