deal with spam

it was bound to happen sooner or later. I was hoping later. we should gather prior art / how other systems do this. I'm a fan of reverse captcha generally, maybe we just start with that?

Start with the linked forum thread and gather prior art on spam prevention in forum systems, including reverse CAPTCHA approaches. The issue does not name files, tests, or an entry point; first define the desired approach and scope, then establish what successful spam handling should look like before implementation.
