No, but it does show how vulnerable all ip's, i.e., all of us, are to
attack via blacklists.
I note that deliberate.com is still blacklisted by Paul's
intersight.com system, even though I went to the url and filled in the
form long ago, and, even though there can not be any legitimate claims
of spam against deliberate.com.
Blacklisting is not a good idea.
Or, if you want to use a blacklist, use it for an additional piece of
information to factor into your heuristic, not as a sole reason for
OK. I'll try to be quiet now and do my work.
