I've submitted a PR for NostrHub which adds WoT powered up-vote and down-vote for NIPs. https://gitlab.com/soapbox-pub/nostrhub/-/merge_requests/9 But is seems that neither @Derek Ross nor @Soapbox have published their preferred Trusted Assertions provider (nor have calculated scores for their network) . You should talk to @david about doing this via Brainstorm ... and then the weighting of upvotes and downvotes will have a sensible default (in the case that an end user hasn't published their own preferred TA provider).
