Dolls House & ex colleagues
Used to be an unfortunate search term.
Back in the day when looking for Dolls House bits & bobs for the sprog, many results were not for small dimension houses, furniture, dolls etc. but were brothels / smut sites
Being UK based I had not realised likelihood of doll with the US double meaning
Though fortunately this was on home PC
On work related theme, a long time ago (late 90s), a bloke was sacked for their downloads - not sure if it was usenet new content grab or whether it was spider & download tool (he was a dev so quite possible he had written his own downloader) - My boss told us about culprits dismissal reasons and just said it was automated background download of pr0n content, so culprit was never viewing anything on his PC (so nobody would spot anything amiss if they walked past him). Culprit would then copy files to external storage (back when external device access to PC far less locked down than now). That caused company to actively inspect what sites / content were accessed by people (he was caught because amount of bandwidth and amount used outside of break time triggered investigation, that later led to discovery of the type of content) - amazing how lax things were back in the day.
