I've been in many 'banter' orgs, primarily made my Chris. Orgs such as 'PLIP' a parody of UKIP where we forced black players to pick cotton on the fields, or when we made the BBC and just read out lefty bias news all evening. Even when we made Asda in the office.
These orgs created some of the best moments in making friends and memories. Some of my most funnest times on the server and with others was whilst being apart of a joke org.
Heck even Metal Gear Solid roleplay with Tom Hill when we used to sneak into bases and just hide was loved by basically everyone.
It's not like these joke orgs are a epidemic.
Maybe it's because you've never been part of a proper one?
