How about telling them that your friend applied and got the 30,000? Aren't we your friends?
That is a much better way, but there is a good chance they'll say that when he applied it was still valid but it's not anymore. It would probably still be possible but a lot harder.
Edit: Either way I was only asking out of curiosity as I just did a 3bm for SP,SW and UA, and I still have an active freedom (35k signup).
