Facebook for life

Interesting article in the NY Times about how hard, near impossible it is to delete your account on Facebook. Citing a group in Facebook of about 4,800 members just on that very matter. Now it brings two questions:
1. how do Facebook deal with local privacy laws where it is mandatory to be able to delete all footprint of yours with a single email? like in Europe and France in particular?
2. how can you be willing to leave facebook... with a group on facebook? ;-) The egg or the chicken? who's leaving first...
