Tumblr is a social networking microblog.
Tumblr allows for blogs that require logging in to view (https://memories.tumblr.com/) and password-protected blogs. Tumblr also has "private posts" that can only be accessed from a direct link ().
Since 2018, explicit content has been officially banned on Tumblr; any new blogs hosting flagged posts can only be viewed when logged in. Its icon is replaced with a generic icon and the blog can only be viewable in the dashboard (rendering any custom themes and the blog archive inaccessible).
Tumblr has irregularly and manually run "jubilees" for freeing up the names of blogs that are inactive. ()
Users can change their account names into the format used for deleted accounts. Specifically, USERNAME-deactivated-[Any amount of digits, 0-9]. Users who do this are inaccessible via their main account page, or directly linked to posts. Their posts will still show up in searches, and their "archive" URL will work. This doesn't seem to have an effect on the API, and tumblr-utils will still work just fine. For an example of this tomfoolery, see the archive page of user "diediedie3344-deactivated-204913".
Another quirk is that Tumblr accounts that appear to be on a different domain name are still accessible at, and show up in searches as, their account name. Trying to go to any page on the accountname.tumblr.com end redirects you to the same page on the custom-url-here.com page. For an example of this behavior, see user "homosethsual" which redirects to ranpos.star.is
In December 2015, Yahoo put their Tumblr service into the "decide on" category in their Action Plan, according to their 2015 shareholder presentation.
In June 2017, Tumblr tightened up "Safe mode", which limits "sensitive content" to all users below 18 years old and the viewing of blogs marked as explicit, potentially causing a major move-away from Tumblr due to Internet Backdraft from its users. Given Yahoo's tendency to ax things that become less popular than expected, it might be important to keep an eye out for it.
As of 30th of July 2017,
it is no longer possible to access NSFW accounts outside of https://tumblr.com/blog/<name> URLs. Attempting to access an NSFW account normally will now cause infinite redirecting. NSFW marked Tumblrs are inaccessible to signed out users.
On 12 August 2019, Automattic acquired Tumblr from Yahoo!/Verizon Media.
In July 2022, Tumblr announced automatic conversion of GIFs to MP4s (the original GIF is available by changing the URL), upsetting GIF makers ().
In November 2022, restrictions on content were loosened after the introduction of the ability to sort posts using "Community Labels", although "visual depictions of sexually explicit acts remain off-limits" ().

Migrate your Tumblr
If you have a blog on Tumblr, you may want to migrate its content to Wordpress. You can then easily export all the content in a usable format, keep the Wordpress blog as a backup, or even jump ship. An easy and comprehensive tutorial is available at https://kinsta.com/blog/import-tumblr-to-wordpress/
As you probably heard, Tumblr is fighting users and archivists. Please limit your concurrency to 1 per machine/IP address.
As the sources above are incomplete, blogs to be archived can also be submitted using this form.
