Hello everyone.
No, I didn't get scammed, and I've never done this, but kind of warning people. I've read stories like this on other forums.
Goes like this. You take someone with 1337 weapons (Lets say, Tormented Tactics Shield) out to an explorable area. You somewhat gain their trust, and you want that person to drop it on the ground and pick it up again. The person with the weapon drops it, and as soon as he does it, the other person uses a skill like Return (All adjacent foes are Crippled for 3...7 seconds. Teleport to target other ally's location.) on them, and quickly picks up the item, and logs off. So now the person has NO Tormented Tactics Shield, and guess what, this
sometimes will not get you banned, even if you report. Heck, even if you
do get banned, a simple e-mail to NCSoft will let you access your account again, although I do not know whether you can keep that item or not. Even if you don't, it's not like it's going to go back to the original owner.

Makes me wonder what ArenaNet does to those items.
