Austrian law student Max Schrem’s class action lawsuit against Facebook for alleged data privacy breaches continues to growth with 25,000 now signing on in the lawsuit.
Mr Schrems alleges that the way the social network monitors its members’ activity on and off the site puts it in breach of EU laws.
As part of the claim, he also alleges that the company co-operated with Prism, a US surveillance scheme.
Facebook has previously denied knowing about Prism before it was mentioned in leaked US government documents.
The company has, however, acknowledged complying with national security requests from US government agencies.
