Thanks. I am looking in how I can throttle sign ups by IP address without causing problems for legitimate users.

I've yet to try the "hidden fields" honeypot.

ASP.NET behind Azure Frontdoor.

The only pattern I see consistently with such sign ups is that their name and email does not match if you read closely. I don't know enough about Azure Frontdoor functionality to be able to fix this myself.
