How many sponsoring circles have you detected already ? I can't believe people able to be sponsored aren't doing background stuff to make sure they get free $5K a month from github, since it's a simple as doing a reciprocal sponsoring. Heck, anyone with a bit too much cash can just offer to be payed to sponsor, let's say you give me 1 unit, I sponsor 0,9 upon payment, you get 1,8 from github. TL;DR : really surprised…
GitHub is vetting applicants. If they do get hoodwinked, they are at least getting hoodwinked into giving money to somebody they thought was doing worthwhile work to begin with.
Also, in the "paid to sponsor" scenario they'd be hoodwinke into giving money both to someone worthwhile and someone totally unknown to them. I'd be really curious to know the technical or legal possibles responses.
