People whining about how they're hurt by losing search position inevitably turn out to be spammers or other lowlife that have been trying to use "SEO" or some other shady practice to artificially inflate their search position.
I have a slang dictionary site that's currently being penalized by Google for showing citations of slang use gathered (by hand) from media.
With the penalty, Google sends 1/3 less search traffic. And I whine about it. But I'm not a con man.
