Did you get a browser error when trying this? It might be because you left the www in the URL. I had to remove that and replace it with old, and it works. The rest of the link structure is the same on both old and new reddit. I even tried it from a VPN just to be sure it wasn’t seeing my logged in cookies, and in a private browsing window where RES isn’t allowed to run. Worked fine.
The fact she didn’t say it was VSJ, but that she keeps her IP makes me think it is a smaller company.
