Yeah, if you put Goog's nose right onto them. Otherwise, not.

As I said in another post: If Google were to penalize all those "minor issues", then many good no-spam sites would fall out, and the real spammers who know their CSS would stay in. This is not in Google's interest (as I believe).

We have seen that Google is - in many cases - not able to detect even the most blatant spam. Do you think Google catches the small fish ("there is a 4 percent chance that this might be spam ... lets kick it out") because it can't get the big ones?

I don't buy that.
