What often happens is that we see more data indicating that the IP is bad than data indicating that it's good, and it's harder for low volume IPs to climb back out. We're always working on improving the models (usually without any fanfare), and low volume IPs are one of the areas we're focusing on.

Thanks for putting this up -- there are already enough misconceptions and rumour; generic good advise is nice to see.
