Does anybody here know anything about the legitimacy of Constant

In preparing a list of HOSTKARMA_W violators for Marc, I noticed a
very large amount of spam, coming from completely different companies,
was sent through constantcontact.com servers using their "Safe
Unsubscribe" feature.
After some web searches, I decided to use the unsubscribe feature, but
apparently I needed to unsubscribe every email address with every
company that uses constantcontact.com. To me, this means it is quite
clear that Constant Contact's anti-spam policy is improperly enforced
at best and flagrantly ignored at worst.
The biggest problem is that they're well seeded in the DNS whitelists,
including HostKarma and IADB, and they often use SPF, which gets the
"OK" from my double-check in khop-bl.
Before I write a custom rule to add points to anything passing through
a constantcontact.com relay, I was wondering if anybody here had
thoughts on this.
(Note, questionable custom rules like this get tested on my production
servers with near-zero scores, then real scores, and /then/ they find
their way to my sa-update channels.)
They're cluefull; they monitor SPAM-L; they use one of my email
addresses as a spamtrap. We don't use them, but they're still aware
enough to email us and ask if something looks dodgy. Good folks, IMHO.
