Based on personal experience and numerous data points here on FT, SD, FW, etc. you could title it, "Any and every bank will fire you with enough MS activity." Question is... how much is too much? And even if some posts $xx,xxx.xx as their upper threshold before getting AA, there is no way of knowing whether or not Bank X will fire you for $xx,xxx.xx - $y,yyy.yy

Best advice I've heard and followed: don't sh!t where you eat, find a smaller bank/CU and be open with them: I'm going to deposit and withdraw money to make spending bonuses on reward accounts; I'll keep a healthy balance in the interim, and show receipts whenever you ask.
