David,
The fine for putting out bandit signs is not a $1,000 fine. It is a $1,000 fine / sign / day. The information on the sign is prima facia evidence in the case. And yes, a friend of mine was caught and prosecuted. I STRONGLY recommend you DO NOT place bandit signs in Fort Worth (other cities have different laws).
