Not much as the sites talk to eachother. In this case .world is just where your account is located and where you sign in. You can use it to post to communities from other sites as well.
I tried last year but a month back I got banned for 'ban evasion' after going on a 5000 mile roadtrip for a honeymoon and using the sketchiest of unsecured wifi APs.
This time around I realized I can set the default sort in account settings to the top posts in the past 1 or 6 hours, def give that a shot, neverending stream of new posts, zero reason to wanna doomscroll reddit ever again
