In college (2010) I built a honeypot to test this. Simply adding a field that blocks anything that doesn't run JavaScript worked in most cases. And that makes sense: a lot of this junk is garbage like malicious WordPress plugins that crank away to just fire off HTTP requests.

But you don't need proof of work to stop that abuse. The simplest JS with a fallback to a "I'm not a bot" checkbox would do the trick. So you're defending against folks that do run JavaScript, but...not fast?
