Easiest is to use another service:
Squarespace, Wix, and Wordpress.com are usually the most common ones. These services provide the ability to create a site yourself with little technical knowledge.
Squarespace makes this clear, NSFW content is a complete no go and grounds for cancellation of your account.
Wix doesn't appear to mention content exceptions in their Terms of Use, but their tooling is clumsy and can be frustrating to use.
Wordpress.com's TOS likely also does not mention NSFW content. An [old support forum thread)(https://wordpress.org/support/topic/adult/) suggests that it is allowed. This service also is the most portable, as you can export your content and self-host in the future if that changes. Wordpress.com also tends to be more reasonable when it comes to legal threats from the MPAA and RIAA and other copyright mongers.
