I recently purchased a copy of scrapebox, and I've trying for many days to do a successful harvest. With proxies enabled, it doesn't harvest a single URL. Sometimes it shows that the scrape is competed without actually harvesting any URLs (all keywords not completed) and sometimes it shows the error 403. I use No Hands Proxies to scrape public proxies, and they work really well with GSA SER. I also downloaded the free version of Gscraper to test the proxies and it could harvest URLs at 20-25 URLs per second. So obviously it isn't a problem with proxies. i have been in contact with scrapebox support and they haven't been able to identify the problem yet. They only reply every 24 hours to each of my email replies so correspondence with them has been very slow. Things I've done to try and troubleshoot are: test server connection, adjust maximum number of proxy retries, adjust connections, etc. Nothing works. Help me out here guys!
