Combined with their recent hack and their exposing of team names a few months ago, I'm becoming wary of using Slack. They don't seem to have a security-focused culture, and that's a massive problem for a communication service.
I accidentally signed into another organization's channels on Slack. Had to delete and re-make an account to get into my organization's channels. Apparently there were already concerns about Slack not taking security seriously, so it wasn't really all that shocking to me. Currently not using Slack, obviously.
Sorry other organization – I hope you guys move off some time soon.
