Boosting reputation is one common issue but, if you were really scammed by a guy, would you , on his request, still give him a good reputation? And even if he or she was your friend, would you still befriend that person?
Trade permits is to ensure that traders take trading seriously and do not troll or hog trade tables without trading etc.
