Where are "All those Tumblr links I see around here"? I don't know what that's about.
As you say, Tumblr isn't allowing nudity any more, but I say good riddance. Back when it was new, there was a level of freedom at Tumblr that you could respect. There weren't any rules, and they were proud of it. Anyone could post anything, and invite anyone to look at it. Sure, there was plenty of pornography, but that was what the users wanted. For a naturist, it was frustrating to see that hardly anything labeled "Naturist" was at all authentic--it was just another word applied to porn. But at least naturist material could be there, on the same basis as any other topic.
Then Tumblr sold out to Yahoo, and the restrictions became more and more severe. And of course, the restrictions didn't make any distinction between pornography and whatever tiny amount of non-sexual nudity existed on the site. And then there was the ethical issue, where most material on Tumblr was copied from other blogs, but originally stolen from some legitimate source far away in the past. That, plus requiring viewers to sign in and claim to be adults, made the whole enterprise unusable for naturism, in my opinion.
So now they won't allow nudity at all. Well, I say it's been worthless for years. A bunch of blogs full of material stolen back and forth, with pornography being dispensed under the name of naturism, is something the world is better off without.
Ed, I'd like to take a look at your blogs. Just don't give a naturist anything to be upset by, OK?
