I use kagi.com as a search engine and it automatically does that for links I click on thru them. I think there is a browser extension for Firefox that will do this for you as well.
One reason I've stopped using reddit entirely. They require fingerprinting you. If you do a good job and they can't fingerprint you, you get that screen. It is NOT blocked by IP of the VPN as some here have said. You can easily see the content through the same VPN while not logged on as long as you have enough identifiable tracking information to reasonably guess who you are.
It's a great test now. If I'm ever let into view reddit now, I must have seriously screwed up somewhere in my security chain.
Reddit has blocked certain IP addresses from accessing its website. (In this case VPN IP addresses) you can use a peer 2 peer network through a vpn provider or tor which would not be on reddit block list.
If you go through my post history you can see I posted the same thing several months ago. If anything we've probably given reddit specific information on what VPNs you and I are using.
