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.
