You basically steal from them (even if the leader didn't set them correctly) but seeing as your posting this you obviously feel you did something wrong and knew it from the start. You may not be banned but next time you have people being rude to you on the server need to remember this cus I am sure word will get around. It also goes further to people wondering why some people can be absolute jerks and not care about others, cus instances like this start to break them down and refuse to trust new people.
