Unfortunately, zap receipts can be spoofed so they're probably not good to use for wot.  The only one that knows for sure if a zap was real, is the recipient that manages the wallet that received the zap.

"This isn't really a payment proof, there is no real way to prove that the invoice is real or has been paid. You are trusting the author of the zap receipt for the legitimacy of the payment." From https://github.com/nostr-protocol/nips/blob/master/57.md 

 It's the same with followers in WoT. People make multiple npubs and then they can recommend each other. 

 True, yeah I always felt like these are both somewhat non starters.. the only things that seemed like they would work would be more like fiatjaf's pyramid, or that notabot project, where people vouch for each other, and when bots are discovered you know the invite tree (how they got in) and can prune it. 

 you can do that with WoT as well, because it's always one dumbass in your list that is at the root of it, cut them out, and their immediate neighbours and voila, clean again

this is why i rage against wishy washy "tolerant" people 

 i'd have to think about it for a while but i probably can cite at least a dozen examples in movies where it was that one "bleeding heart" that doomed the people 

 😂 

 Yeah but following someone isn't the same as vouching for them 

 but anyone who you follow who follows dumbasses needs to be pruned, and that solves a lot of problems by itself

fucking turds attracting flies... psychopaths can smell the vapors of a bleeding heart a mile off 

 even if the zaps are real they can go round in a circle too
