Also: Now I can finally make a nice long daisy chain of this service and Blockchain.info's service. Both restrict resending to another address of the forwarding service but this should work:
Blockchain address 1 (B1) -> BitFast 1 (F1) -> B2 -> F2 -> B3 -> F3 -> B4 -> F4 ->...
infinite miner fees!
Gosh! I din't think of it! That's evil!
But, it will stop after 2 or 3. It check for back transactions too

Since, both the services generate a new address, only 1 tx will be there
