It's been about two years since Tumblr has banned adult content, and there had been alternatives at its wake. I know that artists like me have moved to Twitter and Newgrounds, and there are the alternatives like Mastodon, Pillowfort, and newTumbl (which I am using, but not often; it's more like a backup for my art).
With what has happened over the past two years, with Tumblr almost bought by Pr0nhub (which in my opinion is a dodge in the bullet considering Pr0nhub's purge of unverified accounts), and Tumblr is now bought by Automattic (the company who owns Wordpress), how is Tumblr now, and its alternatives of Pillowfort, Mastodon, and newTumbl?
Asking whether or not Twitter pulls the Tumblr because I've heard of rumors of Twitter getting sued by joyless politicians writing down a lawsuit similar to SISEA.
EDIT: This is about Tumblr and its alternatives, not Twitter. Clarifying the title question.
