Tumblr is dying, the Mastodon project’s developers are bickering, but between it all, everyone still needs porn. Luckily, Mastodon’s fediverse is the perfect safe haven for adult artists, sex workers, and 18+ content creators fleeing from Tumblr’s NSFW ban.

For those unaware, Mastodon is a microblogging software that functions similarly to Twitter. Users can write 500-character messages, or “toots,” as well as boost posts or like others’ content. The site even features a DM system perfect for reaching out to artists, escorts, and other users.

But Mastodon’s most important feature is its decentralized social network. Users can set up their own communities, or “instances,” which can interact with users on other instances. Every user is part of the fediverse, but these communities can be as connected with each other as they wish to be, including not at all.

This means there’s an enormous number of possible NSFW instances that users can join—or particularly tech-savvy Mastodon users can hop in and create their own instances. If you’re interested in seeing what’s out there, here are the best NFSW Mastodon instances.

The best NSFW Mastodon instances

1) Switter

Switter is easily one of the oldest and most popular Mastodon NSFW instances available, and for good reason: It’s a safe haven for sex workers. Switter works like a hybrid between Twitter, Craigslist’s former personals section, and Tumblr, making it a familiar spot for fans of those sites. Escorts, adult video creators, and cam performers rely on the platform to reach their clientele, and there’s an enormous community already available on the instance for both sex workers and clients. Common posts range from photoset updates to classifieds inviting users to reach out. Others advertise for phone sex calls, upcoming cam events, or access to models’ Snapchats.

As for Switter’s appeal, this instance is best for any Mastodon users interested in directly connecting with and supporting adult performers, models, and escorts. For the record, there are over 200,000 users on Switter, making it incredibly easy to find both workers and clients alike.

2) Humblr

Humblr is a self-described “Tumblr alternative for kinky minded people,” and to that extent, it’s certainly one of the best NSFW instances available on the fediverse. Unlike Switter, which mainly focuses on connecting with and supporting sex workers, Humblr functions much more like Tumblr: Users share, repost, and chat about 18+ content to their feed. It’s also an enormous community too, with over 64,000 users.

Kink and fetishism porn is particularly common on the instance, with accounts like @BDSM hosting bondage and S/M material for users to check out. While Humblr mainly features porn with women, there’s also a fair amount of erotic material with men, such as user @Mrchwkz’s feed. Whether you’re queer or straight, there’s a lot to love on Humblr if you’re eager for porn.

3) Displaced.social

For queer men wandering the vast fediverse after the Tumblr NSFW ban, displaced.social is a solid choice. Hosting just over 4,000 users, displaced.social calls itself a “safe, open space focused on those in the NSFW LGBT+ community.” While relatively small compared to instances like Humblr, displaced.social hosts a pretty active community for gay men in particular, with the local timeline alone featuring a bottomless feed of erotic and pornographic depictions of men.

There’s a wide variety of users to check out on displaced.social, too. Accounts like @male_eyegasms feature tastefully erotic depictions of men that are sure to excite queer men browsing the site. Meanwhile, more explicit accounts like @shall, or “SPANK BANK,” regularly post gay porn for folks that like something a little bit hotter and a little bit more not-safe-for-work. For gay men who want a photo-browsing experience similar to Tumblr, displaced.social is a must-visit alongside Humblr.

4) Art Alley

Also known by its URL “artalley.porn,” Art Alley is one of the best Mastodon instances for creating, following, and commissioning 18+ artwork. While Art Alley isn’t just for adult art, the Mastodon instance welcomes NSFW content and lets users openly talk about sexual content. It’s prevalent on the community’s local timeline to say the least, making it a great way to quickly find, follow, and support the fediverse’s 18+ artists. And unlike displaced.social and Humblr, Art Alley’s users are very sociable, making it much easier to build new friendships.

Art Alley quickly became popular with Tumblr users fleeing from the NSFW ban, and to this day, the community fosters an inclusive and approachable environment where artists regularly chat with one another and their fans. Content ranges from tasteful nudity to specific fetishes like vore or furry characters. But unlike other NSFW instances, Art Alley users usually hide adult content through content warning (or CW) filters. This means users can choose to be exposed to what kind of adult content they want and avoid certain fetishes they may be uncomfortable with seeing. If you’re longing for Tumblr’s inclusive, queer, and accepting artistic community, Art Alley is a great choice.
