you are not proposing a federated amazon, this is just federated ads and/or reviews.

how to process payments? how to ship goods? how to handle refunds? how to handle contestations?

please you can’t just make anything federated. this protocol is built for social media and struggles to take over that sphere, we should focus on one thing rather than throwing random stuff at the wall hoping it sticks (cough federated tik tok cough)

this is an icky issue because lemmy sends votes with empty addressing, so remote instances should count them but not show them to anyone. however mastodon (and *key) sends likes with empty addressing too, but considers them public. lemmy is (surprisingly) right here and should request that the rest of fedi respects the protocol and hides stuff based on its addressing. maybe open issues on mastodon and friendica

also this issue probably exists when seeing lemmy posts on any microblogging instance

please have some introspection: you’re being offended over some internet argument and complaining about a whole community. is your respect conditional on never wronging you?
