Hello, I write the same script before, more over this script can come to all founded urls and parse for links on expired domains :) I can modify it by your request, but main problem that is need list of proxies, because google not give access to get many requests from one IP.
Regards Denis.
P.S. My script have admin panel, save result in MySQL, use PHP and CURL for multi threads. But as I write can modify by your request.
