Good advise. For various reasons, a majority of IP addresses within a CIDR of any size being abusive is likely to cause the CIDR to be blocked. While a majority could be considered as being half right, the existence of the "bad neighborhood" demonstrates a lack of oversight for the entire CIDR, which is also fairly predictive of future abuse. -Doug
