Poor being used in both its meanings, because I do feel sorry for the poor bot because it has a lot of work to do, but it's also really badly written.
Some background for the non-tumblrites - in December 2018, Tumblr banned "all images and videos depicting sex acts, and real-life images and videos depicting human genitalia or "female-presenting" nipples", in one of those phrasings that smacks of a large corporation trying to sound "woke" and failing miserably.
To judge whether or not previously posted photos were illicit they used a robot.
19 of my posts were flagged by the poor little bot.
A woman breastfeeding
Two knees with friction burns from astroturf
A baby having it's heart beat listened to with a stethoscope
An article on spear-phishing, which I grant has a risque photo
Topless (male) Croatian football hooligans, though I grant he has bigger boobs than me.
The US 4 x 200 m freestyle women's team hugging, with the shocking sight of Katie Ledecky's back.
A man sunbathing
Muhammad Ali's obituary
A photo of two hands being held out.
Anthony Joshua celebrating winning the Commonwealth belt.
A photo of Rowdy Roddy Piper bodyslamming Hulk Hogan
A picture of a belly button (admittedly probably female).
A picture of a fully clothed Buffy sat on top of a half naked Spike. Risque, I grant, but again with 0 female boobage.
Mark Cavendish on a TdF podium
A sabreur fleching, which I grant is unnatural but fencers are literally covered from head to toe (except the off hand).
Tommy Voeckler cycling
Tommy Voeckler ironing.
Sebastian Vettel signing autographs.
Woman in bathing suit watching the Monaco GP. (Again, no boobage)
Of the 19, one contains a female breast. Which is breast-feeding, an activity explicitly excluded from the ban.
Mostly the poor little bot has great difficulty telling male wrestlers apart from naked women, and has an active hatred for photos of Thomas Voeckler (allez Tommy!).
These were all flagged before you could appeal, but after it became obvious that the poor overworked bot couldn't tell its etcetera from its elbow (or a woman from mid-2000s Chris Jericho), they started allowing appeals and all were cleared on appeal.
In that time, I reported 8 porn accounts.
Since then, I've had to report another 6. I've also had a variety of other posts flagged. Tumblr seems to only flag posts as you either post them or edit them.
Chris Jericho and his female presenting nipples
Henry VIII and the wives meme version (no idea why)
Henry VIII and the wives meme version (again)
A completely clothed Alundra Blayze winning the WWF title
Morticia and Gomez Addams flirting
A collapsed MMA fighter
The same collapsed MMA fighter after they've already reviewed it, when I reblogged it to a side blog.
Peter Lorre advertising "Mad Love" (no idea why)
A woman's hand with a wedding ring on it
Bayley and Alicia Fox wrestling
A bat, your actual Chiroptera.
The Pope praying
Yankees and Red Sox not playing baseball in the rain
Indiana Jones
Buffy and Willow talking
Arty black and white photos of actors preparing for the stage - possibly due to half naked Tom Hardy
Smiling Mads Mikkelsen - Obvs. his smile is NSFW
Henry Cavill's naked chest - because his cup size is larger than mine
A farming robot
You'll note 2 of those aren't even human. And one of them is the Pope.
I was going to post this anyway, but they've just flagged a photo of a statue which, while it does feature breasts, is of a naked angel praying and is theoretically covered by the art exception. I appealed but got told my appeal failed. We all know the appeal is just another bot, I suspect a slightly better but more calculation-expensive bot, so I have emailed and am trying to get a human to actual see that she is made out of granite, but I am not holding my breath.
So far, the poor little bot has 19/19 false positives.
