I agree. Although Usenet.farm is not as useful as it seems at first glance. They say 3000+ retention but that's only for text. Actual files they apparently only save for up to 70 days and only heavily accessed files for longer. That said, their Eweka still mainly fetches almost as much as if going with Eweka directly. The 2600 max retention can be a bit of a disadvantage if looking for very old niche stuff, but you might be able to find that stuff with the blocknews account if paid for a year.

Are you finding the posts to begin with on Geek? How old are the posts that are failing? if they are under 3000 days then they are most likely taken down and it really wont matter which service you use. Copyright requests hit them all. You either need to find a repost on geek or on another indexer or move on. Some stuff is just targeted much more than others. If they are really old posts then you may need an account with higher retention (still no guarantees its there though). that is where the frugal blocknews account with yearly comes into play.

I like Eweke. It has a lot of content!
