Can someone help me out..worried about an exploit

I posted this in the bug section..but just curious if this is a one-off i had or if it is repeatable. Don't want this getting through to OB if so.

Details of what I did in my thread here:

Basically I could equip a level 20 req item when I was only level 9.
