They can be abused certainly, but I disagree that they are a
"counter-example".  The best use of RBLs that I've seen are the ones
that analyze the body not the headers.  Look at the proposed
*destination* that the spammers wish you to click on and block
messages containing those, as opposed to blocking the source which has
a limited and detrimental effect in these days of botnets.

RBLs have a bad name because of those (overzealous) systems which
block entire subnets, even including hosts that are known not to be
spammers in order to compel them to move to a "better" host.

I think the consensus was that everyone hates it.  :)
