Yup. I've complained to the main Spamcop guy about that. Spammers
harvest "honeypot" addresses (among others), forge those addresses as
the purported sender of the spam email. If the mail bounces, or is
rejected because that address is not allowed to post to the list, or
is sent a subscription confirmation (for an email sent to the
listname-subscribe-request address), or if any kind of reply is sent
back to that address, then you get listed by Spamcop.
His response can be summarized as "too bad, you shouldn't respond to
spam".
My attitude is that "if a honeypot has been compromised, it's no
longer a valid honeypot and should be closed". He agreed with the
premise but disagreed that spammers forging the honeypot address
meant the honeypot was compromised.
The only solution is to find a very accurate and very fast anti-spam
tool, set it up in a SPAM_EXIT, and set BOUNCE_SPAM=0 (the default).
Unfortunately, I have yet to find a very accurate spam filter, let
alone a very fast one. Setting up a spam filter will help, but with
today's anti-spam technology, some spam will always get past and
generate bounces or replies that will get you listed in SpamCop.

That's been my experience too, but it does get tiring to be
constantly on your guard.
