You're an admin in your organization's external workspace, which is used primarily for Slack Connect conversations. Recently, you received several complaints about inappropriate messages posted by a user at another organization. The user has posting permission only, and their messages are in clear violation of your Codes of Conduct.
Which step should you take to eliminate inappropriate messages from this user moving forward?

A. Disconnect all shared connection points with the offensive user's organization using the Connections menu.

B. Remove the user from all of their channels in bulk using the External People menu.

C. Mute the offensive user in each of the channels where they have membership using the channel Settings menu.

D. Encourage users who reported the messages to use the /leave slash command in each conversation with the offensive user.
