Does anyone know of a service that can be used to determine whether an IP has been associated/used by one of these proxy services? It would benefit my company to be able to detect these types of fraudsters

Very interesting service, but sadly I cannot sign up for a trial, due to not possessing a US telephone number, which for some reason is required. That said I am a researcher at an Internet measurement and security group. Any chances for a cooperation?
You say it yourself:
> Residential proxies can be impossible to detect.
The appeal of residential proxies is that the traffic comes from legitimate user networks. So how do you detect malicious usage there?
Moreover, it must be a game of whack-a-mole to keep your lists updated, as these services pop up all the time.
Honestly, for assessing risk of individual users, my worry is that the only good option right now is to use tools that require lots of data on the user, like recaptcha v3. You could set up a honeypot that tries to catch as many IP addresses implicated in proxy activity as possible. Maybe that second one would be a good company idea.
