It seems you have made up your mind already!

You will only get this message if your IP address is on their "black list" for some unknown transgression....
So have you made up your mind it is censorship?
I don't know how much knowledge you have on how to run a web site, but in broad detail, this is how it works. I'll use free-ware for my explanation for fear of offending name brands.
They talk with Apache. You can block certain IP addresses at the Apache level already. Most people don't do that. At this level, you can create chats like what we have here.
Apache can talk with Tomcat servlets. These are the little smart guys which connect via JDBC and ODBC to databases. So if someone wants to go beyond simple chatting and get something back from the database, a call is made to a servlet.
Apache and Tomcats can be setup in a many-to-many configuration for load balancing purposes.
There are cards in the servers call LAN cards, you can have multiples in an Apache server and groups of IP-addresses can be shunted to different servers. LAN cards can cater to more than one IP-address, but that's another story.
SOme of the important things CD need to achieve are:
(1) load balancing - this is a very busy site;
(2) shunt certain IP-addressed to the appropriate servlet container which have special privileges.
A lot of work is still required for the "load balancing" technology with automatic fail-over and recovery of processes so that no transactions are lost.
With you DSL, try not to switch it on and off because it you do, you most likely end up with a different IP address. Now I suspect CD gives preferences to "regulars". It is quite possible that you get shunted to a busy server.
And yes, CD does have censorhship and ban some people, but CD does not ban as many people as does countries like Australia where your cannot post to the major broadsheets without the messages being vetted and approved first.
One other newspaper that I am aware of, the NYTimes.com, provide a similar service. You will find that we quote from NYTimes.com a lot here.
I have also get "site busy" from American ISP providers. Eventually I get through.
Other technically-minded forumites are welcome to add their two cents worth - this is only a very high level introduction using free-wares.
Okay there, chief?
