It's not link buyers you need to worry about, it's preferential treatment to the undetectable spam sites.
Example: ehow got sacked with Panda but howstuffworks took off despite most of it's automotive articles being copied from Publications International, Ltd. magazines. Their incoming links aren't paid but they sure can leverage discovery properties. How to compete with that ?
I'm pointing to publicly available stats with the above btw, not pointing fingers at any person or company, it is what it is.
