Gianni Meca has successfully used VPNs to avoid GS bans. He and the Italian folks are using the following Google Chrome plugin: https://dotvpn.com/en/download/chrome/
He advises that one may need to try a few VPNs at first, before finding one that is
fast and has unfrequent bans, but that there are quite a few with these
By using VPNs they could even run in queries in parallel.
Thanks again Gianni!
