IF YOU HAVE NOT DELETED YOUR TUMBLR, GO AND CHECK.
For the last couple of days, if you went to a site that was adult, you would get a message
This Tumblr may contain
and the dashboard would just explain the new normal, and you could go no further.
NOW, when you go to a site, and then
when you click the go to my dashboard, you get your normal tumblr feed, and the right panel states this is sensitive material, but it does permit you to VIEW this site
and when you go their, most of what existed on this tumblr still exists, you just cannot get to archive.
Give it a try.
