According to the Norwegian technology website NRKbeta, Facebook has reported to the Data Protection Authority for violations of European privacy laws in Norway, the Netherlands, Belgium, Spain, Portugal, Italy and Greece.
After revealing the scandal Facebook-Cambridge Analytica, the largest social network admitted that data was affected by 87 million members or about 27 million more than originally reported.
The company reports that mainly citizens of USA (sic, because European legislation is stricter), but it is now clear that the data collection also affected users from all over Europe
Complaints to European data protection authorities, which were filed simultaneously by several consumer organizations, say that Facebook does not adequately protect the data of its users, that the company is inattentive to third parties' access to the data it collects, and that it has not repaired nothing but knowing about the 2015 leak.
The European Data Protection Authorities (in the case of Greece, we are talking about Home Privacy Policy or Hellenic Data Protection Authority) may force Facebook to stop or change some of its practices.
