The filtered results file also continued to invite me to “comparison shop for unprotected anal intercourse,” which may be something the filter's authors will correct in version 2. And what if one is too many? One approach is to use one of the various text based algorithms that lie behind censorware initiatives such as SurfWatch ( For example, AltaVista uses its index of problem terms to provide a “Family filter,” which effectively removes the triple-X offender but also all nine of the worthy sites that the unfiltered search found. So, not shirking, I discover that this search returns only one triple-X header on both Google and AltaVista and nine worthy sites.
As I start to look around for the web angle to this theme, my intuition suggests that entering the search term “unprotected anal intercourse” into a search engine may return sites whose orientation is not primarily medical. This week the BMJ publishes a short report that shows an increase in the prevalence of high risk sexual behaviours for the transmission of HIV among gay men in London.
