So, your a content creator who makes not family safe and/or queer content and you're worried about puritanical USian corporate social media completely destroying your ability to publish your work.
You decide you need a website. But don't know where to start.
Well, 
Websites for NSFW content creators
First of all, I'm not new to this. I'm the admin for eschergirls.com, which was originally a Tumblr only blog until they were bought out. Websites and infrastructure are also my day-job. So this isn't untested advice.
re: Websites for NSFW content creators
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.

The downside is that all of those are, you guessed it, a very common legal target. Company lawyers love to target other companies to bully them to remove content. And sometimes, that means you're out of luck when they decide it'll cost them more to defend you, rather than cancel your account.
This means you need to be defensive. You need to either get help from someone technically adept, or develop some technical chops yourself to keep your site and your income up and running.
The more defensive you can be, the harder it'll be for corporate lawyers to silence you. It's a *cost* game; you're little, they're big. So, you need to be fast and flexible so that it costs them more than it's worth.
re: Websites for NSFW content creators
To be fast and flexible that means you need to set up your site yourself without using social networking, or site-building services. It means you need to build it yourself.
First thing: Domain names. That URL you type into your browser? That's a domain name. You can actually buy a domain without buying into a service or a hosting company by going to a Domain Registrar. There's a lot of these, such as GoDaddy, Network Solutions, and even Google. May favorite is Hover.com -- they cost more, but the advantage is *privacy*.
When you register a domain, you need to do so with your business or house address. This is *publicly* available and can be easily searched from tools such as Whois.com. This is why I like Hover, as the additional cost points that address at themselves, rather than you. This makes it more difficult for company lawyers to target you directly without an expensive process of serving the registrar first.
Domain names typically cost $10 a year, although some can be cheaper or much, much more expensive. When you do find a domain name you like, you can sign up at your registrar of choice.
A backup domain name on a second registrar may be a good idea, if you believe you're likely to be targeted.

@socketwench btw, if you want some ideas for domain names, scroll through https://en.m.wikipedia.org/wiki/List_of_Internet_top-level_domains
The primary caveat is that not all registrars support all domain suffixes. There's also a bunch with additional restrictions.
