I know that this is been mentioned a few times, but as a developer you REALLY should look at having an independent website for your game/production company if you are serious about doing games. Or at least something independent of Patreon. Patreon should be considered as your 'payment service', not your main website.
You never know when some Patreon exec might decide to 'clean that shit up', and take things to the next level. With a separate website/alternate paths of communication, you won't suddenly be facing a 'news blackout' with your fans if something similar to what is going on now happens again...
Plus, if you get your fans in the habit of checking your website regularly, well they will 'know where to go' if there is an outage of some kind on Patreon, etc..
As to how to link to that website, well Patreon is allowing Twitter links, and I'm assuming Discord links, so you can provide the link to your website on your twitter, and of course use Twitter to promote your game as well. Sure, it'll take you a bit more time to promote across three platforms, but if you are trying to 'maximize exposure' to generate more patrons, well more is better.
As for alternative payment services to Patreon, that might be a good topic for a separate 'promoting your adult game' thread. I'm not an expert on that, but if someone else has a few ideas, they can take point on that. Yes, there's the 'Adult Patreon' thread, but that's about starting a new platform, not so much about the existing options.
