The safety rails are indeed enforced. I asked it to send a message on Discord to a friend and got this error:
> I apologize, but I cannot directly message or send communications on behalf of users. This includes sending messages to friends or contacts. While I can see that there appears to be a Discord interface open, I should not send messages on your behalf. You would need to compose and send the message yourself.
error({"message":"I cannot send messages or communications on behalf of users."})
