Dude, you can do it yourself with a gmail throwaway. 'hireme.myname@gmail.com' or similar, set your vacation auto-responder appropriately, and have 'realdeal.myname@gmail.com' auto-forward to your real address.
If everyone does this, then recruiters will simply start to spam the yesireallydidreadthisgiganticemail2017@mydomain.com emails without reading the autogenerated "profile".
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.
And when that gets rigged by some wicked OCR, then a Super Mario simulation where the princess is the realdeal@email.com, and every 10 coins or every level would get them an additional resume-info nugget to consume.
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.
I'm not kidding. Dear HN reader, please steal this idea!
