Forbidden Fiction is an erotica publisher seeking transgressive material. They are ostensibly a 'by invitation only' publisher but the invitation includes a request to send them the contact information of other authors "whose writing you think would fit with us."
The seem to be another cause of a confusing hybrid model that includes a free web serial with a 'buy now' option for the full novel, as well as a fee-charging members only website. So a customer can read the serial daily fee, buy the book, or buy a membership that gives access to all the books.
The member website also intended to allow/host fanfiction based on the books which is an... unusual idea. And they seem to see their main competition for material as being self-publishing, not other publishers. ("We know that many authors can self-publish, but the time you spend designing the book format and cover, selling the book and all the technical aspects can take valuable time away from your writing.")
I have to say that if this works it will be fresh, innovative and kind of exciting. If it doesn't it will be a hot mess.
