zoom hacking

Last night on a zoom program about art, I was zoom hacked. We were well into the program and someone started scribbling over the slides. Then the scribbles turned into nasty words. Somehow I was able to stop it and then it happened again a few minutes later. Someone identified who had done it so I removed that person from the meeting. (It was only a first name and don't think there is anyway to tie it to an email.) I then clicked on every button on my dashboard to enable all possibilities of further interruption.
