It provides a better audit trail. It is trivial to setup PTR records, and
DNS admins should be clued enough to know that their configuration must be
consistent. When all IP addresses have PTR records the admin can determine
more quickly the possibly offending ISP. Yes, I know, I could query RIPE,
but registrant information may not always lead to the desired person.
