A few months back I built a cryptographic alternative to CAPTCHAs called Ghost Keys[1] that uses a small donation as proof-of-humanity. For donating you get an anonymous keypair that works across services without repeated CAPTCHAs. The economic friction doesn't scale for bot operators, and donations fund our non-profit[2].

In the event ticket situation, how does this change the economics compared to just adding $1 to the ticket price? (or whatever your minimum donation threshold is)

It would add $1 to the ticket price, the goal is more to replace CAPTCHAs (which cost essentially nothing to defeat these days), but you're right that it wouldn't be a silver bullet in the ticket scalping scenario.
