Booble, the "adult search engine" hasn't been removed from the Web at the time of writing, but it isn't really a search engine, either. The launch press release here says "each of its 6,000 + listings have been edited and classified by hand," so it doesn't claim to have searched the Web. I'm not even sure it searches its own database: all it does is retrieve what look like advertisements for paid-for porn sites. So it's really a marketing story: Booble.com has been hugely successful in getting attention for a string of boring porn advertisements just by using a design based on Google.
It was probably very easy to do, too, if you already had all the information in your Guide to Online Erotica at SirRodney.com.
