When your session is force ended for "abuse" you get neither the response nor a refund

Security, games (think weapons, PVP, attacking, etc), sometimes even asking it for a security review of some CRUD code it wrote itself

I asked it about a “yellow background cell” in Excel and it spewed a book at me. Then it solved the issue.

What a joke. Must make it pretty easy to poison a session, you don't need to persuade the model about anything, just trigger its security controls, ideally after as much context as possible, but before it has generated any useful output.
