Valleywag highlighted a post from Bangalore-based programmer Tanay Sai, who found a loophole (which Slack called a “feature“) enabling anyone to see which groups Slack customers had created within their organizations just by entering an e-mail address with the company’s domain.

This loophole (or feature) has not been fixed.
