Spam RBL's are being attacked on the legal front which puts black lists in

Spammers will never win a case against RBL operators, because the RBLs
themselves do not actually block anything. It is the the individual
organization that decides what RBLs (if any) to use, and therefore it is
the individual organization which sets up the blocking that is preventing
the "legitimate solicitation of business".
