@TwilightHours, I've raised this to Zoom as a Feature Request. I do not have any insight as to whether or not this will be implemented.
We had an occurrence in an Alcoholics Anonymous meeting on Saturday morning. Vile racist CHAT entry and awful adult-only screenshots kept flashing up. The bomber bouncing around with the raise hand feature. This is OUT OF CONTROL. It cannot be a difficult fix. Add it to the Participant Activities list of can/cannot. This SHOULD be simple. We love Zoom, but you must deal with this feature. Allow Host/Co-Host to disable raise hand option.
