how block transcription auto-bots from zoom meetings - this remains huge Zoom security exposure

[essorkm]

unknowing users subscribe to a freemium autobot that attaches to their calendar and then interjects itself into any video meeting on their calendar

this is a huge security exposure to our organization

there are at least 5-6 vendors; and the list is growing; most of them are NOT on the Zoom Marketplace

zoom settings do not appear to be working

• blocking domains of the autobots does not seem to work, eg block read.ai
• setting a captcha does not seem to work either

for usability in our 10,000 volunteer organization, we prefer to avoid hassles of forcing registration/authentication, we use embedded passcode in the zoom URL link

• captcha is acceptable [if it worked];
  • but not mandating entry of the meeting passcode
