Time Warner is Breaking DNS

Time Warner, in their infinite wisdom, have decided to go down the path of Verisign. This morning, I accidentally punched in an invalid domain name and was greeted with a Time Warner page saying "lslakjdflskjdflsdjf.com is invalid." Below are some screenshots.

Figure 2: the url redirects to Time Warner's page, giving them an opportunity to register the name/make money from advertising

Many people's programs and scripts rely upon ISPs and registrars not doing things like this. Obviously Time-Warner is not a registrar so their redirect doesn't affect as many people as Verisign's did, but I still find it ludicrous. Thoughts?

Update: Apparently someone else has done a thorough analysis on this already. It looks like TW did a bad programming job here. Something that I'm going to play with in my spare time ;-).

I'm just amazed Comcast hasn't started doing this yet. I'd say switch to OpenDNS, but, surprise, they do the same thing.
