I use scrapebox at very low volumes - 3000 comments to blogs every 10 days or so, and use a random pack (servers in several different cities) of 10 exclusive private proxies (no limits in these). Recently after doing a comment blast (all diff names, emails and spun comments for each) I went to do a Google search... Google is asking me to fill in a captcha form to confirm I am human (twice in a row). Now, since I have not used any other BH tool or any other tool that works on volume processes, in my mind, this can only mean on thing.... Google is able to trace back past the private proxies to my main IP (which is fixed at my ISP) and/or there is an issue with how SB is scraping the URLs - but even then, Google should not be able to detect back to my IP if the private proxies are working right..I would think? Anybody?? Would I be right in assuming the issue is most likely with the Private proxy provider if Google can trace back to my computer IP and asks me to fill in a captcha when I do a normal search on Google? I don't want to mention the providers name in case I am wrong and unjustly do some PR damage so I would like to see what the most likely cause is first and work from there.
