Every user exists on a spectrum of engagement & activity. So any WoT will need user input, and I think profile level labels might be too broad, but really, most users won't engage at all.

Unless... "trust engagement" is made a first class citizen of consuming a post. Posts are immutable, but people change all the time, so the trust should be tagged to posts to be most effective.

Naively, a swipe left/right feed could maybe generate some good insights, as users are forced to make a binary choice at every post 🤷‍♂️
