LUXEMBOURG — MindGeek, the parent company of RedTube, denied allegations Monday that it divulged user information to third parties as outlined in a story reported by Die Welt.

The adult entertainment conglomerate also said that it has no affiliation with the German law firm of Urmann and Collegen, which, according to Die Welt's article, sent hundreds of warning letters to surfers "who have allegedly seen several pirated porn [movies] on the portal."

According to the Die Welt article, Urmann and Collegen attorneys sent out waves of warning letters to RedTube users, asking them to pay 1,000 euros in compensation for streaming "pirated" videos as well as legal fees of 150 euros and investigative costs of up to 250 euros. Titles such as "Glamour Showgirls" or "Amanda's Secret" were mentioned in the letters.

MindGeek emphasized Monday that even IP addresses of users were never forwarded to any third parties at any time.

"Our security measures and user privacy has always been a top priority for RedYube,” RedTube Vice President Alex Taylor said.

RedTube, one of the most prolific adult tube sites on the web with about 25 million daily users, is actively pursuing an "in-depth investigation into the serious allegations that have surfaced in the media recently," MindGeek officials said.

"RedTube pursues stringent privacy requirements and maintains the highest industry standards of privacy protection to secure not only their assets and properties, but to provide comprehensive protection of their customers’ data when visiting a RedTube-owned site," the officials said.
