New world, new problems....
Zoom-bombing. It's a thing. Just when you thought it was safe to video-conference with your boss - and BANG - inappropriate content of the pornographic/racist/anything-else-they-can-think-of style, pops on the screen. Public meetings are most susceptible, but everyone using Zoom should follow some simple rules to avoid problems.
Zoom has released guidance for users who want to protect themselves from Zoom-bombing. For public meetings, Zoom reminds users that when you share your meeting link on social media or other public forums, that makes your event public, and this means that anyone with the link can join the meeting.
Zoom also suggests users avoid starting public events using their Personal Meeting ID (PMI) because "your PMI is basically one continuous meeting and you don't want randos crashing your personal virtual space after the party's over." Zoom suggests generating random meeting IDs. Zoom also suggests using the Waiting Room feature, which allows hosts to control who enters the meeting.
They also offers numerous suggestions for managing participants.
