A real provider is one that provides mail for real users, as opposed to 
someone who plays RFC language lawyer games.  I only have a few dozen 
users, but I can assure you I use a whole lot of different filtering 
approaches including DNSBLs to keep my users' mailboxes usable.

I must say it's pretty amusing that someone who works for the organization 
that published the original DNSBL seems to be ranting against them.
