Every now and then, some tumblr blogs disappear. But I think it may have to do with the fact that the user cancels its blog, or that the blog gets canceled by tumblr if the user does not pay a fee after a free trial period. I don't know how tumblr works and if what I have just said makes sense.
Most, if not all, sexually oriented tumblr sites are now set to be non-viewable without the viewer having a tumblr account of their own.
