It's more than a porn ban, though, it's an "adult content" ban. IMHO because Tumblr chose to make the ban broad instead of focusing on commercial pornography, this made the controversy a lot stronger than it needs to be.

As it stands, Tumblr is not just banning someone's stash of hardcore sex videos. It also is banning, say, a casual vacation photo taken on a beach where topless sunbathing is acceptable (due to the explicit ban on female nipples except for a few narrow contexts). On a more "adult" level, it is also banning stuff in between the two categories, like say boudoir photography (which is usually adult in nature, sometimes erotic / titillating, but is usually not explicitly pornographic.)

Even the "any content that depicts sex acts" seems vague. Would something like, say, Rodin's "The Kiss" -- https://en.wikipedia.org/wiki/The_Kiss_(Rodin_sculpture) -- be flagged? I don't know, it depends on what the auto-algorithms sees as a "sex act" I guess. Certainly if you were an artist that dabbled in any sort of erotic drawing / painting, the vague definition would probably be a worry IMHO.

(Tumblr is already 13+ already. Commercial crass porn is one thing, but I personally don't think there is any problem showing a 13+ year old this Rodin sculpture or a casual beach shot where topless sunbathing is acceptable.)
