So here's what we do

We amass catapaults, an arsenal of catapaults

We collect piles of rotting meat

We assemble in front of banks

Just remember to frown visibly, and do not cooperate with the authorities!

You can't fuck with the message because  THERE IS NO MESSAGE

100% foolproof

We wait for customers to come out of the bank, and fling the rotted meat at them to express our distaste for usury
