I agree, but with sites that do not have much authority (aka PageRank), it's difficult to determine attribution when scraped content is coming online just as quickly as an original post. Googlebot will generally hit a site several times a day, but if it's hitting the spammer's site first or if the spammer site has more authority, it's a long uphill climb to get things turned around.

I should also point out that this is just one thing to consider amongst the other points already made by others.
