Proton is the privacy-centric company behind Proton Mail, their VPN software isn't terrible -- you can leave it off most times without problems -- and their free service, while limited, doesn't come with Gotchas. I think it could be useful to every GOTD regular... to get the key for some giveaways you visit a web site, fill in the blanks, and get the key via email. Sometimes their email is blocked so you have to use a different email address, but sometimes the page where you request a key also records your IP address, so if you request a key using another email address you're blocked. Turn on a VPN and hopefully you're good to go -- VPNs and proxies have a limited number of IP addresses available, so it is possible you'll get an address that's already been used for that giveaway.
