Huh, I enjoy a muted slackbot. Are you sure it’s not just that you can’t mute slackbot when a personal at-mention is “injected” in slackbot’s message? Because yea that’s annoying af. That comes from slack app developers not understanding the platform though. At-mentions should only be used with intention, and obviously an at-mention in a DM is completely unnecessary.
I was trying to keep Slack notifications unmuted in case my manager needs something from me, but I was just getting too much useless crap from Slackbot. Finally I had to mute it completely and tell him to call my cell if anything comes up
