Not much of an imagination, to be honest. He really didn't think that one through.
All the law firm has to do is go, "Hey, all these $1 payments are false. Please do not process them" and the bank goes "Oh, ok, yeah, thousands of $1 payments is pretty fishy. We won't process them."
And it just makes TPB look like assholes, and makes their possible re-trial even more pointless. It is a juvenile stunt and reflects poorly. :/
