One of the largest streaming porn sites on the Internet made waves late last week by announcing via Twitter that it was considering sponsoring a professional gaming team. But officials at some of the industry's largest tournaments say the company may not be welcome.

YouPorn, a member of the MindGeek (formerly Manwin) portfolio of porn sites, stirred the waters on Friday, asking its 117,000 followers, "Do we have any competitive '[League of Legends],' 'DOTA2,' or 'HeartStone' players following us? What do you think about YouPorn sponsoring a team?"
