Plenty of forums don't require an account until you want to write a post, if all you wish to do is consume content you're free to read all you want. Historically this was the default on the web, it's a relatively recent phenomenon for sites like instagram/fb to require login to even read anything. YouTube manages to deliver plenty of entertainment value without a login to this day, until you try to look at "mature content".
