The JewWatch petition again
Although the petition easily exceeded its stated goal of 50,000 signatories, Google did not of course censor the results, for reasons which are obvious to anyone who knows how Google's search algorithms work: they did produce an explanation for those who don't.
Of course, that algorithm cuts both ways, and a web campaign of links to the Wikipedia page on Jews or on Judaism, using the link text "Jew", means that a search for "Jew" now returns those pages as number 1 and number 2 results, and not JewWatch.org. So there is no need to continue to circulate the petition email. The problem has been solved, although if you want to include a few relevant links on your web pages, that could help to ensure it stays solved.
