I don't follow your argument about getting pwned.

A user could leave malicious instructions in their instance, but Clawbert only has access to that user's info in the database, so you only pwned yourself.

A user could leave malicious instructions in someone else's instance and then rely on Clawbert to execute them. But Clawbert seems like a worse attack vector than just getting OpenClaw itself to execute the malicious instructions. OpenClaw already has root access.

Re other use cases that don't rely on personal data: we have users doing research and sending reports from an AgentMail account to the personal account, maintaining sandboxing. Another user set up this diving conditions website, which requires no personal data: https://www.diveprosd.com/
