Thanks for noticing. Sometimes we spend months working on stuff that nobody notices.

How do you know the room names?

Right now anyone can add/remove participants in any room. There is no policy enforcement functionality, it can be added but requires more development. But as the conference room URI must be known, the chance of bots doing stuff is minimal as they cannot guess the rooms in use, only those invited in the room know the room address.

For example, I create the room:

2142145214214214 at conference.sip2sip.info 

and I invite you and others, how can a bot figure this out?

Yes, it would be nice to have such controls, but without extra developments they are not possible out of the box.
