I came across this curious paper taped to a wall in the historic part of Lisbon. I've translated it below, leaving out the name and passport number:
Do You Know This Man?
If you don't, consider yourself lucky. If you do, then it's best to exercise caution. His name is *****, he's German, and his passport number is *****. He mostly hangs out in the areas of Príncipe Real, Bairro Alto, Castelo and Graça, and he's one of the biggest conmen to ever come to Portugal.
Never put money into his hand! You'll never see it again. . .
He came from Germany to escape from the debts he had there. He says he's a student, a teacher, a translator, a painter, but he's a salesman (The problem is that he sells contraband). . . Be very careful!
He never liked to work and has always depended on women to support him. He has betrayed friends and conned customers at a business that he created and then abandoned.
He specializes in biting the hand that feeds him. Furthermore he's homophobic and incapable of respecting anyone's privacy!
