Google and low quality guest posts

[ProjectLabs]

In the aftermath of the Penguin and Panda monsters a lot of blog networks seem to have been devalued by Google. It seems logical that spammers will flock to low quality guest posting next. How do you think Google will determine which guest post links to devalue?

Thanks!

How do you think Google will determine which guest post links to devalue?

The ones with crappy content that have keyword anchor text links pointing to other domains.... and the domains that they point to have lots of other crappy content on lots of other crappy blogs that have keyword anchor text content.

"The ones with crappy content that have keyword anchor text links pointing to other domains."

Would you say it's safe to assume that both of these would have to be implemented for it to be devalued? The anchor text AND the crap? I mean, keyword anchor text pointing to other domains is a good practice used by many valuable blogs--it helps your blog posts be more informative.

I don't know how Google will do this - or if they will.... but if I was the boss at Google, each crappy post on the blog would increase the odor of the entire domain... and anchor text links would have their juice cut by 90%.

I say flocking to low-quality guest blogging is a bad solution to Penguin update. Penguin was not primarily about banning blog networks. It was about banning over-optimized links and link schemes. So Google will use the same tactics here: too much anchor text, too easy to identify!
