I tend to agree with that, although I also have more problems with the fact that
it implies that any RBL is ever perfect.

A better wording was "spamcop.net RBL listing ip's that send nonspam by mistake?".

Which of course still has the problem of assuming that listings that affect both
spam and nonspam are or should extraordinarily rare. They aren't rare, they're
commonplace in all RBLs.
