There's no coincidence that we refer to them as:
Challenge-Response Authentication Programs (abbrev. CRAP).

In fact, the only time I've ever seen someone use one, the guy was a
spammer himself. (and I had to use it to complain about his spam).

You probably want to blacklist subdomains of gacybertech.com (return-path
and hosts).
