I found something interesting when I check a few hours ago. I was logged out to set the stage. I goto the main page it works. I use the search bar to find a sub and it works. But all the links on that subs page to related subs direct you to the "You have to log in"

So I was like, hmm what if I type one of these links into the search bar and see if I can get the link that way? It worked I could access the link that previous required a log in

I'm sure they will close that loophole and reddit will continue its decline...
