Tangent: is it ok to put sensitive stuff on slack?
I mean sure, they're legally prevented from snooping, but considering there'd be no way to find out if that confidence were breached, is it ok to have confidential discussions or upload sensitive documents or private keys?
I think this is a situation where you need training in best practices and checklists etc. rather than asking questions on HN.
Marginally I don't think it's a problem but given that most people don't treat slack too carefully I wouldn't trust it regularly (Not slack itself but people gaining access).
