alt Hacker News> Stolen ID can be found for a lot less money than what a day in a scam farm's operation will bring in.
Well, in that case, Google has an easy escalation path that they already use for Google Business Listings: They send you a physical card, in the mail, with a code, to the address listed. If this turns out to be a real problem at scale, the patch is barely an inconvenience.
So they'll have a lead time building up a set of verified developers. These scams are pulled by organized crime syndicates, using human trafficking and beatings to keep their call centers manned with complicit workers.
Now they'll need to pay off a local mailman to give them all of Google's letters with an address in an area they control so they can register a town's worth of addresses, big whoop. It'll cost them a bit more than the registration fee, but I doubt it'll be enough to solve the problem.
