Hi,
I have gone through your requirement of domain scrapping.
I want to know more details about the project which kind of domain scrapping you are doing.
One is crawling the web with a bot and copying all content you find, or perhaps specific content that you are looking for.
And other is I think the more common usage is scraping for expired domains. In other words, checking domain expirations, and snatching up the domains when they are not renewed, in the hopes of extorting someone for an inflated renewal cost.
So please feel free to discuss the details so that I can understand your requirement.
