Whether you are using your local IP only...or, multiple quality private proxies,,,,,you are being blocked because of the frequency of requests for each proxy you are using....Whether you are using 1 proxy or 100 proxies....Set the request time out (1 thread only) for 60 seconds....Run 200-500 requests.....If all goes well....reduce request in 5 second intervals....With the proxies I utilize, I find that a 'sweet spot' is typically 40-45 seconds...even with 50 dedicated private proxies...However, sometimes I have been able to get things rolling with a setting of 30 seconds...I typically leave it at 40 or 45 seconds per single thread request....Very, very slow...for thousdands of requests...but, that is what I am living with....I have not tried rotating proxy service though...Just datacenter, static, dedicated private proxies only. Note - the request speed directions I am providing were provided to me by the great ScrapeBox expert...'LoopLine'....
