Remove BlackPlanet site. This site has always returned a false positive. I looked into it and discovered that the site returns the exact same text for a claimed or an unclaimed username. The site must be rendering all of the different content using Javascript in the browser. So, there is no way distinguish between the results with the current design of Sherlock.
