The Pharma hack Krug describes: doesn't it show up a weakness in Google's ability to detect spam, if hacked sites show up in search results at all? They exhibit classic cloaking techniques, feeding search engines certain content which it hides from human visitors.

Surely you'd expect sites like that to get penalized pronto? Isn't Google able to detect this algorithmically?

The hacked sites go to considerable lengths to evade detection. That said, we made recent changes in April/May reduced the level of hacked sites bearing malware in our index by 90%.
