So far, he's been scraping Nostr users posts and feeding them into a Microsoft / OpenAI "moderation api".

If Microsoft gives the thumbs down to your note, Rabble's bot sends out an automated complaint. Like an automated DRM takedown, but with no teeth.

Some relays will delete notes based on complaints, but other than his own relay i dont think anyone paid attention to the bot.

I think he's taken it down for now, he wants paid staff to supervise it but hasn't found the right investor.
