"Stoozing" (hadn't heard it called that before) hasn't been profitable in a long time, unless you're willing to take huge risks (in which case, there are better ways to make leveraged bets). I haven't seen a balance transfer offer with a transaction fee of less than 2% in quite a while. Even at 1%, you'd just break even.

Even if you are willing to take on a moderate amount of risk, most people - even those with good credit and decent incomes - are going to net a few hundred bucks per year off this thing, max.

It is a really poor way to make extra income.
