Bitcoin? It doesn't really have a crowdfunding site per se, but "people who moral guardians hate" is basically the number two reason for its existence, right after "people who lawmakers/financial regulators hate".
Sure, but bitcoin may be hard for her grandparents friends at church to figure out, for example. Heck, I've worked for tech companies, and I can't figure it out. Gofundme is comparatively easy to explain.
True. There's probably a business opprotunity in there somewhere for a payment processor with a policy of never disputing chargebacks, since that's the main excuse used to kill crowdfunding/patronage platforms that don't play along with moral guardians.
