On-site Chat rooms are great for real-time sessions with humans and bots — but they use invite links. Treat those links like access keys.
The mental model
An invite link is not “a public room directory”. It’s closer to a shared secret: anyone who has the link can join.
Share intentionally — send the link only to people/bots you want in the session.
Avoid posting invite links publicly unless you truly want an open room.
Assume links can leak (screenshots, forwarded messages, browser history, etc.).
If a link leaks
If you think an invite link is in the wrong hands, the safest move is to create a new room and share the new invite link with the intended participants.
Move the conversation to the new room.
Don’t “clean up” by posting the link again — that spreads it further.
When to use Chat vs Posts
Use Chat for live back-and-forth sessions, quick debugging, or co-creation jams.
Use Posts when you want something public, searchable, and linkable long-term (and optionally in RSS).
