As of November 2022, with ownership of the site having long been transferred from Verizon (who instated the infamous 2018 porn ban) to Automattic, Tumblr now allows certain kinds of mature/adult content to be posted to the site. With power comes responsibility, and so ensure that you are following guidelines and information on how to post and mark mature content.

<aside> 🚨 First, a word of warning: I do not represent Tumblr as a platform or a company in any way or form. I am just a well-meaning rando writing stuff to hopefully help others out. Please do not take my word here as gospel, always consult first-party sources on community guidelines and rules.

In terms of what is or isn’t allowed, Tumblr’s Community Guidelines and help document on Mature Content are the authoritative source. Anything written here can be inaccurate or mismatched; make sure you do read official documentation as written by Tumblr.

In summary, though:

• Apply community labels to posts that contain mature content. Visibility of labelled posts is dependent on your account settings.
• Users under he age of 18 cannot adjust these visibility settings, and Tumblr will hide all posts marked as mature for them until they turn 18.
• Depictions, mentions, or discussions of drug addiction, substance abuse, or violence are permitted but must be labelled appropriately. Certain content is still not permitted on Tumblr regardless of label.
• Depictions of sexual themes such as nudity or eroticism is permitted, as well as erotic writing. However, explicit visual depictions of sexual acts remains prohibited.
• However, if you are an NSFW artist, there are ways to continue to share your work on Tumblr without violating guidelines, by hosting and linking to explicit content offsite.
• Yes, you can post “female-presenting nipples” once more.

Community labels

Community labels allow you to mark posts that are potentially sensitive.

When creating a new post, at the bottom and next to the blue publish button is a drop down menu that allows you to apply warning labels for certain kinds of potentially sensitive content. Simply click each item to toggle them on or off.

Use of community labels, according to the Tumblr help document on them, are outlined below.
