Okay, let's assume you're right, and the MAPS folks are the fairest in 
the land. Then how do you explain our case? NetSide was blackholed 
between Jul 13, 00 and Feb 27, 01, then the block was mysteriously 
lifted, only to be reistated on May 11, 01. The 'evidence' is the same,
a single relayed message from a Corecomm customer to
That is Dave Rand's personal playground. Dave is also a founding father
of MAPS, and was recently (like Apr 30) elevated to the reigns after he

The type of cartel that was created here is against anti-trust laws in
the US. That's what is commonly referred to as conspiracy to restrict trade.

Wouldn't it be nice, or at least fair for everyone to know who's listed?

So now, how has my business bothered your business? It hasn't. I don't
recall any complaints from your service. That means we at least manage
and monitor our servers pretty effectively as configured, and we're not
unrepentent spammers. But we dared to be different. Face it, it's really 
our philosophy that angers you.
