Or maybe he's trying to trick someone in trading 200 mursaat tokens (or other items that look similar to real ectos) for 200 keys.
No. He posteted WTT my XXX ecto for your XXX zkeys; and i was quick to repond. The trade went soomth and was over within 10 seconds. But the shock still lingers on.
He did it so you could come here and post about what a great deal you got.
He probably had a bunch of ectos stolen from hacked accounts and needed to dump them quickly before ANET caught up to him... What better way to move hot items then to sell them low.
