kms.js

/*
kms (kill my slack)
This function had the intended effect when pasted/executed in Chrome's browser
console on Slack's "Manage members" page
(https://computer-lab.slack.com/admin)  on 12/22/2018.

I’ve found that deactivating all non admin users in a workspace (effectively “deactivating the slack”) 
during the holidays is a good way to give everyone a break, especially in noisy public slacks. 
Unfortunately, slack does not provide a “deactivate user” endpoint in their API (at least for free slacks), 
and manually deactivating all the users is a pain, so I had to go the “paste in browser console” route.
I might add some sort of reactivation function ... after the holidays.
