On my site www.rechtzweinull.de, where I regularly write about the relevant internet law in Germany and Europe, you find a short legal analysis of facebooks recent promotion strategy.
As it is only in German, I would like to repeat the conclusions here in English.
As German privay law can not be waived be the facebook terms, it ist still applicable.
Publishing the members names to promote the own plattform without the express consent of each member is - of course - also illegal in Germany. The privacy statement is not sufficient to justify this strategy.
It seems, that facebook already has stopped this practice.
However I ask myself, how facebook could start such a campaing, obviously without consulting a competent lawyer.
