First of all, everyone, and I mean EVERYONE, needs to turn in the pages of scrapers found listed under the affected domain names.

If enough people turn all these in, google may ban the individual permanently. It’s happened before, and that person could not even get a white hat site listed anymore.
List one search page where all of the entries are scraped, and note the number of sites on the right top corner of the search page
in my case Results 11 – 20 of about 31,400 for gamesandcasino
so 31,000 under this search.
You can play around with how you type in the site URL and find alot more.
If all of us complain that a search for site abc turns up tens of thousands of listings that are not at all ABC, google will act.
Google is sick of that crap itself. It may help them find some better ways to weed these out.
