What about 1% of people doing this? Or even 0.5%? That is easily enough to live off, and enough to slip under the radar.

To me, getting this done on interesting domains seems to be the hard part. For people with their own domain, getting a separate server to deal with email for that is some hassle. You can't really do this on a generic domain either, cause that looks a lot less professional. Signing people up for gMail accounts might work, but that's probably against google eula. I'd guess the same for other webmail services that are at least somewhat professionally acceptable.

Best way I see is to give people with their own domain as easy a time as possible to set up DNS correctly. Getting through DKIM and SPF reliably seems like a minefield though.

then we make them go through an animated slideshow and do a quiz to get to an email address

And when that gets rigged by some wicked OCR, then a Super Mario simulation where the princess is the [email protected], and every 10 coins or every level would get them an additional resume-info nugget to consume.

Okay maybe I took it too far.

Turns out Bowser was just trying to hire a competent plumber.

But at least a few people would be employed making this system.

Got to keep that arms race going!

You didn't take it too far, someone build the first online recruiter focused video game where the prize at the end of each level is the contact details for a more-and-more suitably qualified candidate.

Can I buy more coins directly in the simulation?

And we have AI that can play Super Mario now.
