That's a good point. How does one rate limit correctly in that case?

I don't think it's possible to correctly rate limit IPs behind NAT, at least with NGINX.

Rate limiting by data UUID might actually be pretty effective. I should add that to patchbay.pub.

That might be an issue if someone is using it to deliver lets say settings json and multiple users try to request the file.
