Slack Technologies Inc rolled out a new feature Wednesday designed to build out its email replacement service called Slack Connect, but had to backtrack almost immediately after backlash over its potential for abuse.
The new Slack Connect DM (direct messaging) functionality allowed paid subscribers to invite any other Slack user to a private conversation, accompanying their invite with a customisable message. The problem that many pointed out on social media was that those messages could be used to direct harassment at strangers online, without an easy option to block them because the invites come from a generic Slack address.
