Today I've been able to shut down 697 splogs by reporting them to Google. I've quadrupled my efforts tonight and if Google removes every one of the reported splogs there should be several thousand less splogs in the world tommorow.
I've been tweaking my set of splog processing scripts and it's finding massive number of splogs with much greater efficiency. Perhaps it's working little too well because it found more than 18000 gambling related splogs. About three weeks ago I've reported a mixed batch of about 2000 splogs but most of them weren't deleted. I think Google support staff freaked over the size of the list and decided to simply ignore it. I found out today the trick to get Google to delete these splogs is to report them in a small convenient chunks. Trying to figure out how I can separate out 18000 splogs into some logical chunks is actually harder than finding the splogs in the first place.
