The social network was apparently tracking non-users web habits, too.
Facebook has been fined €1.2 million (roughly $1.4 million) for several instances where the social network may have collected Spanish user data without fully informing people how it would be used. Retuers reports that Spain's Agencia Española de Protección de Datos (AEPD; Spanish Data Protection Agency) found three instances of Facebook not "sufficiently" informing users how their gender, religious beliefs, personal tastes and browsing history would be used.
More than that, Zuckerberg and Co. apparently didn't tell people how data collected from cookies on websites containing the ubiquitous "Like" badge would be used, either. Even if you aren't one of the two billion account holders, Facebook still allegedly collects your browsing information through that thumbs up emoji. The AEPD also found that Facebook kept user information for over 17 months after people closed their accounts.
