There should be a way to turn off @here and @channel. It should be a user-level setting, a channel-level setting, and an organization-level setting. Even if my org or channel doesn't opt out, I should be able to.
Yes, you can mute a channel and suppress @everyone and @here if you want. Still friggin nuts that a chat service can bring a modern machine to it's knees.

There was one specific person who would ask a question, expect an immediate response, and if they didn't get the response they would @here. They were instructed not to do that because it pings over 1000 people, so the next time they asked twice in an hour and when they didn't get a response they said "I hate to do this but I really need a response @here". They were kicked from the channel. Really unfortunate since it's a very useful channel to be in, but @here and @channel is just so disruptive in big channels.
