I'm sure Scrapebox does a fabulous job in scraping on Google, and it still works, just that the proxies you need to use are residential proxies that revolve their public IP address everytime a search or query is sent to Google. I am able to scrape fairly well and no issues, and I can vouch that the scrape results are pretty good from Google.
The public proxies that you harvest from the proxy module on Scrapebox cannot provide enough Google passed proxies, so the only way is to get a paid proxy service instead.
