Would be great to have something like this for filtering adult content from uploads.

FYI in case you didn't already know this, filtering adult content is a massively more challenging problem than face detection.

And the philosophical aspect of what "adult content" is more difficult than the implementation

I thought they solved this on that Silicon Valley documentary?

"I'll know it whe I see it."

It’s not very useful to implement a filter on the client, you have to filter somewhere where you have control, i.e. on the server.

Might not be the answer you are looking for, but there are several companies offering APIs to filter content.

E.g. Microsoft has a Vision API. Per https://azure.microsoft.com/en-us/pricing/details/cognitive-..., it's $1 per 1000 requests (with the first 5000 being free). They also have PhotoDNA, which is free but does a subset of SFW.

PixLab is another option (https://pixlab.io/cmdls).

Google has an API too (Cloud Vision).

If you go down this path, you'll have to do your own research on which service works best and what you can afford.

I'm kind of surprised that the big guys who do image detection (like google) won't open source whatever algos they use to separate "moderate" content from "adult" content on their image search. It's not 100% but works pretty well in my experience.

I'm not saying it's correct, but my first thought would be that it would make it much easier for bad actors to come up with ways of getting around the algorithm.

that's a good point and I didn't think about that.
