Sending the wrong messages to the wrong people
As admins or hosts, you have more control over what messages can be sent to which people. Basically, you can dictate the flow of text communications and audio communications to a certain extent. This also means if you don’t know what you’re doing, you could be sending a message meant for the group to a single person.
Or, in a much worse scenario, you could mean to talk behind someone’s back, only to accidentally send a message in the group chat. If you want to bad-mouth your boss or another colleague, maybe don’t do it in the public chat box. In fact, don’t do it at all!
