In November 2016, an investigation by journalists from the German TV channel NDR showed that WOT collects, records, analyzes and sells user-related data to third-parties, allowing third-parties to identify individual users, despite WOT's claims they would anonymize the data. The data obtained was traceable to WOT and could be assigned to specific individuals. The investigation was based on freely available sample data, and revealed that sensitive private information of more than 50 users could be retrieved. This information included the visited web-sites, account names, mail addresses and other data potentially enabling the tracking of browser surfing activity, travel plans, illnesses, sexual preferences, drug consumption, and reconstruction of confidential company revenue data of a media house as well as details regarding ongoing police investigations. WOT chose not to comment on the findings when prompted by German media with the results of the investigation prior to the publication of the report.
