"Marcus Tandler blogged about a discovery in a German SEO thread at my old time friend's forum named ABAKUS Forums (translated version over here), about a weird loophole that seems to allow you to check if a site is penalized or not, via the Google Toolbar.  Let me show you how it works.  Here is an example.(1) Open a browser that has the Google Toolbar installed, with a PageRank feature.  Navigate to http://www.seo-radio.de/ (as an example) and see the PageRank value is a 5.  Here is a screen capture:(2) Change the URL to http://hyves.seo-radio.de/ and notice the PageRank value jumps up to a 7. Here is a screen capture:Now, what is going on here.  According to the consensus in the thread, there are three values you can get from doing this:PR7 = No Google PenaltyPR4 = Google PenaltyPR0 = Site Banned in GoogleWhat would be Google's rational in having this loophole?  I really don't know.  How can this be overlooked by Google?  I am not sure.  But everyone is in agreement that this loophole will be gone, soon enough.Forum discussion at Sphinn and "^^<http://www.w3.org/2001/XMLSchema#string>
