This is nothing new. Any facebook user has likely seen tons of these on their feed and so it's only somewhat logical to assume that, for your friends, you might come up in a similar fashion.

In fact, isn't this completely related? http://mashable.com/2013/01/03/facebook-settlement-email/. I think what the OP is referring to is exactly what Facebook calls a "Sponsored Story".

I don't think that this is Facebook "impersonating me without my consent". Perhaps it is Facebook "using me to advertise products without my consent". Either way, if I like "Spotify" on Facebook and then some of their posts come up on my friends' feeds because "So and So likes Spotify" then I understand that it is a form of advertising and I'm not going to throw a fit over it.

It's wrong if Facebook says that I like something which I don't. However, that isn't what they're doing at all.

Yes, the OP is specifically referring to "Sponsored Stories" – the concern and alarm is raised because the user has no way of knowing what stories are being attached to their name, or even that its happening at all.

As for your later point, your assumption that all users know these posts are advertisement and that users understand their friend didn't really like a post about 2 Girls 1 Cup – is patently false based on OP's own personal experience. His mother saw a Sponsored Story by VICE about "Penis Waffles" that had his name attached to it. When she saw the post, it looked to her as if he had liked the story/post and urged him to take it down.

I agree this is not new and probably not illegal but definitely misleading since a lot of people don't notice the subtle different between liking the post and the page.
