I am using 20 private proxies in Scrapebox and had my max connections set to 10% of proxies i.e 2 connections. But after harvesting 40k links google bans the proxies. I tried to harvest with 5% max connections i.e 1 connection. It completed a harvest of 140k links. Is it just me, my proxies or everyone else is facing difficulty with selecting 10% of proxies as Max connections?
