Zoombombing is a new form of trolling in which a participant uses Zoom’s screensharing feature to interrupt and disrupt meetings and classes.

Meetings vs. Webinar Comparison
|Description||Zoom meetings are ideal for hosting more interactive sessions where you’ll want to have lots of audience participation or break your session into smaller groups.||– Think of webinars like a virtual lecture hall or auditorium.|
– Webinars are ideal for large audiences or events that are open to the public.
– Typically, webinar attendees do not interact with one another.
– Though Zoom provides options for you to get more social with your attendees, your average webinar has one or a few people speaking to an audience.
– Attendees can engage in Q&A and participate in polls.
|Best Used For||Small to large groups|
(2+ participants) for:
– Team meetings
– Working sessions
– Training sessions
– Educational lectures with high participation
– Attendees are known and trusted
|Large events and public broadcasts (50+ attendees) such as:|
– Town halls
– Quarterly updates
– Educational lectures
-Attendees maybe unknown
