Previous to this date a misconfigured ISP was just not being protected by the BL. Now, it's potentially dropping all mail from anyone because of the typo.
If only. I am constantly amazed at the bozos who misconfigure their DNSBL lookups and don't notice. Many people are just sure that abuse.net is a blacklist, and no matter what I do (try looking up 2.0.0.127.abuse.net) they keep hammering on it. I also see lookups to names with http// in them and just about any other idiotic mistake you can imagine, again no set of responses seems to get their attention.
