The Royal Dutch Tennis Association ("KNLTB") was fined a total of €525,000 for selling the personal data of more than 350,000 of its members to sponsors. The sponsors have then contacted some of these individuals by email and telephone for marketing purposes. Personal data sold included the name, gender, and address of various individuals. No consent was obtained from the affected individuals beforehand. The Royal Dutch Tennis Association ("KNLTB") argued that it had a legitimate interest to sell this data, and as such did not commit a GDPR breach. The Dutch Data Protection Authority, however, rejected this and ruled that KNLTB had no legal basis to sell the personal data of its members to third parties.
