Beggar
From YPPedia
A beggar is a pirate who begs for PoE or doubloons. The best way to deal with a beggar is to politely tell him or her not to beg and tell them ways in which they can earn PoE. Giving money to a beggar is discouraged, as it will only encourage them to continue asking other pirates for PoE.
There is a shortkey which greeters may use to tell players how they can earn PoE; faqearnpoe. While intended to address greenie questions, it also serves well as a response to requests for PoE.
