Search semantics

Ok, I’d like someone to explain what the robot or crawler or whatever it is that keeps searching for “quaint or donkey or prosodic or compels or counterbalance” is doing? Is it a component of some large web-cataloging device, is it using the results to generate some incredibly clever semantic maps of our virtual world, ¿che pasa? here…

Or is it just some smartass giving me a hard time;-)
