Sky Broadband has asked customers not to panic if they receive a letter from Golden Eye International demanding money for downloading porn illegally via torrent sites.
Sky has asked users to read the letter carefully, but it did not say anything about making the payment.
Such practice is termed as Speculative invoicing, where solicitors and companies target subscribers to internet services and demand payment for copyright infringement to avoid having to get into legal trouble.
The process requires the ISP to give the IP addresses to the company. In this case, Golden Eye said that it has identified IP addresses as being associated with downloading films.
BBC cited Golden Eye director Julian Becker as saying that the company was not involved in speculative invoicing, but it is going to send out letters to "thousands" of Sky customers.
"Rights holders… both adult and mainstream producers have every right to protect their content and livelihood from internet thieves".
"We have only written to those account holders for whom we have evidence of copyright infringement," added Becker.
Copyright infringement is a huge issue in the entertainment industry, and previously Golden Eye approached O2 customers to make payment after getting a list of 9,124 IP addresses on behalf of 13 adult entertainment companies.
Back then the company was demanding £700 per film for copyright infringement.
