Yeah, so it looks like someone has created a spambot that creates wordpress.com blogs and automatically starts comment spamming other wordpress.com blogs.
The blogs are almost all "name###.wordpress.com" with comments of "nice work, bro" or "nice work, dude". When you click through the blog text is non-english and has links to other splogs.
I've had around 10 get through akismet in the past few hours
So if you see one, then click on Blog Info >> Report as Spam on your dashboard
