The Dutch DPA imposed a fine of EUR 525,000 on tennis association KNLTB for selling the personal data of its Members.
In 2018, KNLTB unlawfully provided personal data of a few thousand of its members to two sponsors. Data included name, gender and address, so that they could approach a selection of KNLTB members with tennis-related and other offers. One sponsor received personal data from 50,000, the other from more than 300,000 members. The sponsors approached some of those KNLTB members by post or telephone.
