After seeing this so many times in the game, I took advantage of it and made a 500g profit (Silly noobs, DON'T PUT YOUR KROL BLADE IN TRADE AND PRESS ACCEPT.) I will explain this method step-by-step.
1. Wait for the "LF someone to make my weapon glow"
2. Whisper them that you can, and that the weapon has to be BoE, and unequiped
3. Meet them, and tell them they have to give you the weapon first.
4. Hopefully their pea brain mind will make them give you the weapon.
5. /ignore, and run away with the spoils.
I realized the BoE was needed halfway through this, but whenever they ask, hope they got a new weapon, or tell them to, like say, "I can't make this weapon glow, get a new one"
So, yeah, this only works part of the time, when it does, the spoils can be excellent.
