I like when we just discuss about what you ACTUALLY can and can't do per the rules and leave it at that.
According to the rules, no you absolutely can't. Will you get away with it? Maybe. I have no idea how competent AS is in this regard. I do know that we occasionally get new threads from obvious miles brokers asking why their accounts have been closed down, so AS isn't completely out to lunch here.
Calling it "stealing" was not a moral argument; it's just obvious. Asking whether it's immoral to steal is not something that I'm going to get into. But I don't honestly believe that anyone here does not understand that taking something that's not yours is stealing.
