If you follow/trust a person, you can get a list of people that they are happy to say donated to them.
Decentralised #trust should be good enough, when paired with the content duration that seems to work well on Fedi.
BTW we produced a (#)fediFlyer to help people donate bitcoin to #FediverseDevs, in the form of bounties. If you change the flyer at lot (text and images), all we ask is that you remove our attribution.
