The paper talks about DNS modification based on substring matching. That was in 2007. Not sure why it would start applying now. Could be proxies, or maybe someone is trying to bypass China's DNS firewall by offering a DNS service like:
twitter.com.bypassthegreatwall.com
which resolves to the real IP for twitter.com

I guess Chinese hijacking is now being applied to all queries related to twitter, flickr, etc. in order to inhibit the chance of bypassing the block.
