Thought I'd add my question to this thread - don't mean to hijack the thread. When I Harvest proxies in scrapebox, before testing I remove duplicate proxy ips, but if I keep clicking on "cleanup" + "remove duplicates proxies" it just removes about 30 at a time, each time I click on it. Why is that? Why does it keep removing 30 proxies each time I click on it??? Shouldn't it just remove all duplicates when I click on it once and then not delete anything each time I click on it after that???
