There are alot of things that real pirates do that will get you banned from this game in a heartbeat if anyone were to repeat them in the game.
Instead of comparing your tactics to the real pirate world (which doesnt apply) why not compare them to what it says in the games terms of service you agreed to upon signing up to play the game?
Look at rule #1
http://apps.pirates.go.com/pirates/v..._policies.html
Here it is if you dont want to click:
"Respect your fellow pirates - Pirates of the Caribbean Online
does not tolerate any swearing,
cheating,
bullying or overt harassment toward other players.
Disciplinary action will be taken should any one of these occur while playing."
You may see where some of what your doing applies here as well as in the pirate world that doesnt ACTUALLY apply here.
