Yes, and being on the receiving end of that behavior, I hate it. And in slack it is very hard to manage other than turning off all notifications and just shrugging your shoulders. I can't mark individual messages for followup easily, so I have to leave entire DMs/groups/channels unread.. missing subsequent messages. I end up in 50 different channels, 30 different DM groups and 20 1:1 DMs over the course of a week. Some conversations span 5 different channels/DMs as people are added/removed.. Outlook would just have one nice threaded email on the subject. Slack I end up with 5 little red dots on my channel browser pane.. it's a mess. I've now had to institute a policy for myself on escalations that is - if it doesn't come through PagerDuty, it's not an incident or urgent. This in theory, by official policy is correct. In practice, this is like a union slowing down the trains..
