Hey @TheArtOfHealing apologies for the ZoomBoming and experience you had as we take the privacy of Zoom Meetings very seriously. If you go to https://explore.zoom.us/en/trust/trust-safety/ under 'How do I report abuse', you can proceed with the process of reporting and follow up with the rest of the FAQs as you proceed with your reporting.
Per your question, in meeting you have the option to configure these security settings under the 'security tab' as this should help you out on limitations for participants.
