Generally speaking, I keep Shout and Yell in a separate tab. It helps with being spoiler free when new content comes out, since most channels I'd be reading are tells/FC, so spoilers are limited. When I rely on shouts/yells for communication, such as hunt trains, I switch to that tab (where tells/FC chat also shows up) for the duration. Then switch back.

I can't control what other people do, such as how they use chat. But I can control my own actions (tabs). Easy.
