While I recognize that this is (probably) a real bank, very high on my list of things that I definitely do not want from a banking website is "make me feel like you're not serious".
I wouldn't mind the copy writing too much. I'd pay more attention to eg sensible password policy.
Basically, if they allow the same strong passwords as eg GMail, I take that as a good sign. If they have silly restrictions like lots of banks, that would weight much higher in my estimate of them as an online bank than the silly copy.
But ya see, with Redneck Bank, the sheriff's gonna understand if, when they lose yer money, ya just shoot them banker fellers. That tends ta make 'em real serious 'bout what counts in bankin'. Ya know, not losin' peoples' money.
