My guess is if you contact the admin of hostkarma directly and offer to host
a honeypot he might take you up on it. But that still won't give you the
ability to change anything in the database.
I cannot imagine trusting a RBL that allowed any humans to blacklist
something. Whitelisting is different - you cannot trust the computer
to get it right all the time and there's going to always be IPs BLed
that shouldn't be. But allowing people to BL stuff is just opening the
door for attackers to target or retaliate against hosts.
IIRC the Hostkarma list is fed by people pointing a backup MX DNS host
record at *their* MTAs so that they can analyze the traffic and harvest
the spammers doing "use backup MX to avoid filtering on the primary MX". I
clearly recall being surprised that Marc assumed people would be willing
to do that with their email.

No list is perfect. Thanks for reporting it. Although I try to get
everything right there will always be mistakes. Sometimes I do get to
leaning white because false positives are 100 times worse than a few
spams getting through. Probably what happened with that is that the
sender does a pretty good job of stopping spam and after we get 25
good emails and no spam they get white listed. So what a spam sneaks
through is gets past.

[email protected] will work.
If that's still the way it works, then reducing the score to -1.0 or even
-0.5 sounds reasonable. There were a lot of "I did that too" comments back
then.
Maybe the way it works has changed since Marc died.
