I tried a machine learning model to determine if a picture of a keyboard was SFW
it said no, because it detected the escape key as a nipple
I showed it a picture of me holding the laserdisc of Disney's The Santa Clause and it said it wasn't SFW, because of Tim Allen's breasts and my Penis Hand.
of COURSE I tried a thinkpad keyboard, and no, it didn't identify the TrackPoint as a nipple. I'm sorry.
I also tried the other way: giving it NSFW images.
I can't show those, but it did pretty abysmally. it spotted a penis in one, but an image of two people having sex that was shot from the side? marked SFW. A softcore shot of BDSM? SFW

I tested to see if it wasn't programmed to detect clitorises (clitorii?), thinking maybe it the thinkpad pointer is a clit and not a nipple?

NOPE! I tried turning the detection threshold way down and it managed to detect 27 overlapping pussies (their term, not mine) but zero clitorises.

So I guess it just can't detect clitorises. shame

man, this thing loves to mark my thumb as a penis.
I tried running it on some VHS tape covers but instead of noticing the woman in a leotard on the cover, it told me it was NSFW because my thumb at the bottom of the image was DEFINITELY a penis
this is anti-thumb prejudice!

I tried a photo where I was wearing nitrile gloves while holding up a phone, and it didn't mark my thumb as a penis this time!

it did mark my blurry wife in the background as a sex toy, which is more offensive tbh

if I lower the confidence threshold enough it'll detect my pupils as nipples
I keep trying laserdisc covers and it keeps telling me NSFW and then points out the thumb in the corner as a penis
kinda want to run it on my entire photo library and see what it marks as NSFW.
yeah I don't know why that specific pluot is a penis
I ran it on a photo of me holding a box of Rice-A-Roni, and it marked my hand TWICE as penises, and the "A" in Rice-A-Roni as an asshole
MY MOUSE WHEEL IS NOT A NIPPLE

HAH. it failed on my USB penis
This is 100% safe, baby!

(it's a plastic USB flashdrive in the shape of a penis)

maybe it should be a game.
like it shows you pictures like this, and asks you if you can guess where the NSFW detector thinks the problem is
MY CHIN IS NOT A NIPPLE
well, that's enough for me to confirm that I'm not really missing out on anything but not using this sort of nonsense

Someone on blusky asked me to test this image of the kirby slippers.

Sadly it said SFW until I dropped the confidence threshold, but now it can see the penis, pussy, and nipple.

@foone hotdog or not hotdog?
@gloriouscow I did run it on some hotdogs, and it dutifully identified them as penises
