Beating Blackjack

[Mister Mister E]

Ok guys, I have a couple of comments and questions. Assume you bet $1 at blackjack and lose. You can then bet $2 and lose, $4, $8 and so on, doubling each time. As soon as you win a hand, you drop back down to one dollar. Assuming a very very safe bankroll (and this is very important), you would obviously be able to beat the game. My only question is will an online casino ban you if you are doing this in real money games. I would assume they will, but does anyone have any experience doing this? Is it ethical, etc...
Thanks guys
