You're missing out on a lot of sats if you shun the adult content. I can understand not showing it on the homepage by default. Maybe only show it to signed in users and give everyone an option if they want to see nsfw content or not.
The adult industry is always an early adopter to any new tech. Nostr and Bitcoin are no exception. In addition it's an industry that is also often unbanked and therefore has a lot to gain from it.
Just seems like shooting yourself in the foot and shunning a huge market of existing and potential users for fear of being hypothetically judged by strangers.
Your platform your choice ofc but that's just my two sats on the issue.
