You don't prevent spam by letting humans constantly update how much they trust everyone for everything.
You do it with automation:
A bunch of competing algorithms in a free market, updating in real time based on the data users willingly give them. #WoT
quotingPeople don't know how to rate products. Letting them rate how much they trust Alice fir X and Bob for Y is a UX nightmare.

Why ask users to do something (they can't) that competing algorithms could probably do a waaaay better job at?
Almost all data is public and users literally spend money on what they wanna see more of.
Even the most simple algo PABLOF7z (npub1l2v…ajft) could come up with after children bedtime would do better job then humans indicating trust levels ever could.
