You don't always belong to one single community. Maybe you would rather be part of a challenge completion channel which isn't littered with LF or WTB spam, "/join spamfreechallenges". Maybe later on that day you're interested in brushing up on racing strats before the start of a new race, pretty cool to just type "/join racing" to chat to people about a zone you're having trouble with, could even hang about in that channel to pick up other tips and tricks just randomly being talked about. Then after a busy day, maybe you want to finish it off with a hot milf, "/join hotmilfswaitingforyourightnowinyourarea".

Then there's other issues that can be fixed that I've seen crop us recently like trading maps and not being limited by global chat rules saying no trading in global and being unable to moderate trade channels which can be spammed with messages for all types of trades, "/join maptradinginglobal" and the community can moderate to their own standards. Have a problem with "/join maptradinginglobal" rules? Think they're too pedantic? Think they're favouring assholes? "/join maptradinghaven" where the mods are cooler and the drinks are on the house.

Now you can talk to people interested in multiple different things without having to wade through trump/sjw/prescriptiondrugs spam whilst still staying hooked up with your longer term friends in the guild you're in who might not necessarily have the same in-game interests/goals as you.
