You can’t anymore and even if you did, you will get shadowbanned instantly. There’s no way unless you use the well known ones, i guess proton works but not the aliases though.

https://www.freac.org/ is a nice program if you’re going to do that.

Maybe it will get updated later. Btw, old Reddit still works with accounts. There’s something in settings that tells it to switch to new Reddit and it’s usually enabled by default.

Are you talking about those short reddit links? the only way is to go through them on new reddit then switch back to old.
