I lurk in a bunch of Discords for things I'm not active in, but don't want to have to find an invite to if I need to ask a question in the future.
I always have a notification badge on Discord, and I hate it. Too many servers have channels where I get pinged, even though the channel is muting. I'm presuming someone is doing something like "hey @all, play with me"
I ought to be able to register that I will never ever care about this channel. Please ignore it for me.
