You already did this method for 2 months? You are a person with a high level of patience then. The chance to get 18 greens at 2x is exist. Patience, which you already have, and luck are the two main factor to be able to get it. The only bad thing from your strategy is, you did it with faucet. You can be banned before you hit your target and therefore you will waste your time.
I think it's admirable that he's trying to go for it. Would definitely be cool to see it.. I've seen some people that got 18 reds in a row, but perhaps it's easier to lose than it is to win .
But why would he get banned from the faucets? It's not like he is doing something that they won't like :s
