Google still can't detect hidden CSS layer links?

[np2003]

I thought Google solved this years ago, but it seems many sites that use hidden css div layers and implant their anchor text links still rank right at the top of the serps.

I thought Google algo was smart enough to detect these hidden links? or am I giving them more credit to their engineering team?

A lot of sites use hidden layers for dynamic menus.

In any situation it is also possible that Google detects some practice, but just zeros out any effect - rather than assessing a penalty.

It does not zero them out. I can list about 70 websites that rank on page #1 for competitive keywords that have over 1+ million searches per month. They all have thousands of linkbacks via hidden DIV layers.

Google does not seem to be able to detect these links...
