What a follow-based WoT means in the context of social media is whether the followed identity is likely to be authentic and of information-value, not necessarily whether you agree with that identity. (I follow nostr:nprofile1qqsx3tq0ylq9g5mha3h8ch8x4gkka792rmddc65v9law3mdq0un2llqpz4mhxue69uhhyetvv9ujumt0wd68ytnsw43qcev0zp for god's sake)

This stuff about "not needing to press follow a hundred times" and "updating their follow list on the relay every time the button is pressed) has no traction in my mind. One can modify a client to batch follows, like in nostr:nprofile1qqsrjerj9rhamu30sjnuudk3zxeh3njl852mssqng7z4up9jfj8yupqpypmhxue69uhkx6r0wf6hxtndd94k2erfd3nk2u3wvdhk6w35xs6z7qgwwaehxw309ahx7uewd3hkctcpz4mhxue69uhkummnw3ezummcw3ezuer9wchsfrt6ps. What you are describing is personal feed curation, and many intend this to be public. Some people may want a public follow list, and several separate private follow lists (to avoid endorsement), but this is a power-user feature, and probably too complicated for the "average" person.

To separate the WoT feature from the follow feature is an interesting idea, but also likely to never be useful due to lack of use. Normally people have no idea whether a person they are following is a real person, or even an honest person. In that regard, a "trust" button would never EVER be used. The purpose of a follow-backed WoT is not to endorse, it's so others can see what you want to see, regardless if you "endorse" them or not.
