Hmm. Dave (npub1rcn…dw4h) - are spam/AI shows from Podcast Index removed entirely, or just marked as invisible? I was curious to discover how many Inception Point AI shows are there - "only" 8,100 that I can find. And BuddhAI, which you highlighted as adding 500 new feeds in 24 hours, has nothing in the Index at all (or in the downloaded SQL version).
As with John Spurlock (npub1g2v…achf) 's list - if Podcast Index is just a censored list of shows, it removes part of the benefit.
