Tools: Getting off a blacklist?

[Geoff Hart <ghart -at- videotron -dot- ca>]

For the past couple weeks, I've found that an increasing proportion of 
the mail I send from my service provider (Videotron.ca) is being 
rejected as spam by other service providers, most notably those used by 
colleagues in government and at universities. The one constant: each of 
their service providers subscribes to a blacklist service. The 
organization responsible for maintaining this particular blacklist is 
Mail-Abuse (http://www.mail-abuse.org/rbl/).

My ISP's tech support department claims they've already tried hard to 
be removed from the blacklist and have failed. Based on past 
experience, I give them about a 50% probability of being in the right 
and a 50% probability that they really do need to clean up their act. 
Meantime, the folks at Mail-Abuse seem to be entirely resistant to any 
criticism or pressure to change their approach--though I've yet to 
actually reach a human being at the company, so I can't even file a 
complaint about their holier-than-thou approach.

Needless to say, spammers aren't particularly inconvenienced by 
Mail-Abuse--certainly, my volume of spam is only increasing. My ISP 
isn't likely to change its tune; I'm sure they _have_ tried to fix the 
problem, even if they didn't try hard enough. I don't particularly want 
to vote with my wallet; I'm not sure I have any other options for a 
high-speed connection, since the only local alternative doesn't support 
OS-X on my computer.

More to the point, the folks at Mail-Abuse have gotten me seriously 
pissed, and I'd rather fight than switch at this point. What's to stop 
them from blacklisting my next ISP, then the next one, then the next? 
So here's my question: who does one complain to about these things? The 
FTC? The W3C?
