Well, RFCI is more about making political statements about 
standards-adherence than blocking spam, but, with the addition of a 
suitable whitelist, I find it does actually keep out a fair bit of spam 
because spammers aren't too good at being standards-compliant. However, 
this is more of a beneficial side-effect than a primary reason for using it.

As with any DNSBL, anyone contemplating using it should look carefully 
at the listing/de-listing policies for themselves first.

Cases of debatable interpretation (e.g. the roaringpenguin issue) are 
best brought up on the RFCI list where they can be discussed. If 
consensus is that interpretation is wrong, it gets changed.
