On the 28th of this month, I (and everyone else on the site's waiting list) would finally get to sign up on Pillowfort.io (a far better alternative of Tumblr that WhiteMantis introduced me to long ago).
My handle name for this site is latiro-artings for posting my art (and even posting/reblogging art I got from others), if you know where to look on the site.
I strongly recommend signing up on their waiting list so you can get on the site if you're looking for a Tumblr alternative that actually allows NSFW content, unlike Tumblr itself.
