Oh, we don't mind talking about F95 on our Discord. I post the links to my F95 posts in the Discord announcements. Discord TOS prohibits posting pirated content and encouraging piracy, so as long as you're not linking to something that's supposed to be paid and was leaked, or anything like that, you're fine. It's mainly a server safety thing, as breaking TOS can get the entire server shut down. But mentioning the site is fine in our server. F95 has been really good to us as far as not leaking our paid content, so we're more than happy to do frequent giveaways of normally paid content.
The DLC stories are optional romance routes that we intend to release for purchase. Up until release, they're accessible only by T4 supporters and up. Once they release, they're free to T3 and half off for T2.
That being said, we're also painfully aware that there's a large chunk of AVN players who can't support financially or have no ability to purchase side stories like this. We do giveaways fairly often (there's one going on right now until the 24th, giving away the $10 Fantasies Collection add-on for free). Heck, I think we've done 2 or 3 giveaways of Senia alone in the Discord, and she hasn't even been released yet.
Side stories in the WCA format take a ton of work. Heck, the latest H-scene in Senia's story took me 6 hours yesterday. I know a lot of people are rubbed the wrong way by the thought of paid DLC for a free AVN, but I think it's better to have paid extra content and keep the game completely free, rather than doing what a lot of devs do and putting a price tag on the main game once it's completed. We don't want to gate anyone out of playing the main game, and we like giveaways, so there should be plenty of opportunities for people who can't pay to enjoy most if not all of the DLC content eventually.
Hope that answers the question
