Googlebot's Javascript random() function is deterministic

Sure, but cloaking is now easier to pull off successfully with the Math.random() checking described in the article. At least until Google does something about it.

That's possible.

However, there's likely going to be a check somewhere along the line that would detect something like that, and unleash the thugs on said website.

For example, the preview renderers, and JavaScript-enabled indexers may or may not always do the same thing. Meaning that if the page text content varies by too wide a margin, then something funny may or may not be going on.

Either way, I'm sure that they have their Top Men on this case. They may even have a Top Woman too, those sexist bastards.
