That's life.

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.
