I'm just starting out, so please bear with me. Also my apologies if this is not the right place to post this. So here are my questions: 1. How many anonymous and/or google tested public proxies from scrapebox sources will it take for me to mass comment efficiently and on how many urls? I can't afford private proxies right now. 2. How long do the scrapebox sources usually last? I ask because last night I scraped about 80,000 non-duplicated urls and started mass commenting on them using about 750 anonymous proxies (some of them google verified) scraped from the scrapebox sources; I managed to post on 1500 or so urls, although I can't seem to find any proof of them (URL's weren't scraped from Google). If I am using proxies I scraped several hours ago to mass comment, how many of those proxies become bunk? 3. If I scrape from other public proxy sources, how long do those last? 4. What is the best configuration for a slow system. I am operating out of a crappy nextbook tablet with windows 8.1 and 1GB RAM, and running on moderate Internet speed (don't know exact specs, will look into it) I hope I was clear enough on my questions. If not, please let me know and I will try my best to clarify further. Thanks.
