It’s actually very naive to think that Google is going to do something about these kind of links anytime in the near future. After all, how long has blog comment spam been around? Long as I’ve been online, that’s for sure.

And with ridiculous features like Instant, I think it’s easy to see where Google is placing most of its interests.
