Trading XP between players - can be taken advantage of, should this be disabled?

On RPG trading XP between players is disabled, but in factions it is currently enabled. This can be taken advantage of in one of 2 ways 1. Storing XP on alt accounts so you don't lose it on death 2. Getting more value out of your XP. You can trade XP to an alt so you have exactly 30 levels left, enchant an item, then trade 3 more levels back to your main. Since XP scales by level, you get more enchants from the same amount of XP.
