Problems with Tier 3

I don't know if anyone can help me on this but I am trying to build a large list of auto approve sites for my tier three links. I am looking at getting over 25,000. I am using scrapebox. I know the method to get these lists but when I get a list of say 30,000 which are supposed to be already auto approve and post to them, trim to root, then harvest for deeper URLs I always only end up with a few hundred. Where am I going wrong here in trying to get a large number of sites for my tier three.

what footprints do you use? just a custom one?

just the site: one on custom

Maybe you have too many threads, or your timeout is too low. Make sure you leave the timeout at 60 seconds. Also I recommend just buying lists, its soooo much easier. I've bought a few and I can vouch that they are legit. I'd be happy to share 1 or 2 with you, shoot me a PM.
