When many users mute a channel on Slack to avoid useless notifications, but the authors have noticed. So they post on others channels to make sure those users received the notifications. In the long run, those others channels will also endup being muted, since they now throw useless notifications.
Each iteration of this circle increase the number of channels the authors need to post to and the number of muted channels by the users.

A chronic condition caused by repeated incidents of Slack Shaming, excessive @channel pings, or being publicly corrected in front of your digital peers. Symptoms include fear of typing in any channel, cold sweats before hitting "send," overuse of drafts, and the haunting sound of the Slack notification plink in your nightmares.
Ever since I posted that meme in #finance instead of #fun-stuff, I’ve had Post-Traumatic Slack Disorder (PTSD). I triple-check every channel now and haven’t used @here in 6 months

a mental state where you no longer feel guilty for not having responded to messages your co-workers have sent you on Slack. you reach this state after sheer exhaustion and burn out, typically.
