Hi I have a problem with Scrapebox. I had a free proxy and do not harvest the url of google. Why? Now I got 10 paid proxy, and yahoo easily find me url's 40K, and Google has a problem with the 500th. I do not understand this.
Google will ban IP's for hammering it too much. So even 10 private proxies will get banned for 24 hours. To use the Google harvester you need a good source of public proxies that are updated frequently. (And that pass the Google test.)
