To increase your reputatuon go to ANY church say you want to giv dontation and giv 5000 gold. ur reputation will go up MOST OF THE TIME. Also if u meet someone in the jungle, sometimes they will ask for a bit of gold so they will go n tell evry1 about u, giv them the money, ur reputation sometimes go up. to decrease ur reputation ask in the tavern if there's any work, someone will come in, accept the job. then, when ur out on the sea, suddenly attack the ship when u destroy it ur reputation will go down. if u get ur reputation to Horror of the High Seas, cutthroats in the jungle will not attack u!
