Not exactly, it's a WoT relay using relatr as an 'oracle' and a bucket algorithm for rate limiting and publishing policies. It is intentionally built without using NIP-42, all the accounting is based on the authors of the event. We recently published an article about this, you can read it here: https://contextvm.org/blog/wotrlay-moderation-as-a-bucket or as a long form.
Do you have some feedback? We are just exploring this idea, and it's working fairly well. I haven't seen anything inappropriate in the feed
