I think it is best if you are a merchant in a guild that has controlled battles against other guilds. I'm a merchant who doesn't have to put up with any pirates attacking. If I'm reckless and end up getting attacked, I deserved it. If a pirate uses voodoo to learn my strengths and weaknesses then I have no problem. If he uses voodoo to exploit my weaknesses, I will respond with my strengths.
I'm not the model for all merchants to copy. For me, it's less of a game than a society. The game is different for anyone who plays differently. Piracy is the most interesting and challenging role a player can choose. I know that it doesn't fit me. I'm more of a structured type player. I enjoy hearing about the conflicts and some interaction with players on both sides of the fight. I'm strongly against extended feuds since they just end up ruining both sides.
Welcome to the game, princess. Please don't let someone carry you to the top unless fun is not what you're here for. You'll have more fun if you struggle and build up a network of supportive players to learn from while you do the hard part for yourself. The game is in English and I know that many players don't understand the "help" information. Google translate will serve you well while you learn.
