URL Harvester 2008 - Google Blocked

I am currently using URL Harvester 2008 for collecting WordPress URLs. However, Google keeps blocking my IP address. Does anyone know of a way software that will constantly change my IP address so Google won't keep blocking it?

Most of the auto rotator proxy services suck.

IMHO just buy scrapebox. Must better support for scraping.

i admit it , scrapebox is definitely the best chose and btw is pretty cheap
