The esports team sponsored by the adult entertainment portal YouPorn is being forced out of the Electronic Sports League over its ties to a pornography website, reports VentureBeat.

Team YP is getting the gate from the ESL thanks to a rule prohibiting sponsorships by those "widely known for pornographic ... or other adult/mature themes and products." That is according to an email sent to Team YP by the ESL and obtained by VentureBeat.

Update: The ESL has responded in a statement, saying the rule it has against sponsors such as Team YP has been in existence for some time. The entire statement is at the bottom of this story.

Appeals to ESL to reconsider its decision were of no avail. The team even offered to rebrand completely, removing the YP from its name but, VentureBeat said, the new rule came from the directors of the ESL themselves.

The rule only affects Team YP; no other ESL teams have similar sponsorships.

Team YP released these statements on its Twitter yesterday:

We are disappointed by @ESL's decision to ban our esports team. We will continue to strive towards professionalism and transparency. — Team YP (@TeamYPOfficial) April 23, 2016

Thank you everyone for your support. Team YP will overcome these obstacles and usher in an age of equal opportunity in esports for all. — Team YP (@TeamYPOfficial) April 23, 2016

Team YP was born in late 2014 when the Spain-based team Play2Win won the sponsorship contract from YouPorn and renamed itself. It has always been named Team YP. It debuted under that name in a Dota 2 tournament in Madrid in December 2014. The team competed in a wide spectrum of games, from Counter-Strike to League of Legends and Street Fighter.

VentureBeat has much more context and reaction from Team YP about the ESL's decision, but no comment yet from the ESL or YouPorn. Polygon has reached out to both.

Update: An ESL representative replied shortly after publication with the following statement.
