For example this thread
Archelonx started as "ave 80$ AP , need LR"
hello , i have 80$ in my AP account
i want exchange it to LR , PM or ECU
Anyone can exchange for me and offer your rate , pm for me if you interest
here vizhi replied
I will provide $74 LR or ECU.
if you are interested,reply me
generally AP will be sent firstly,and the LR will be sent.
but Archelonx can reserve AP soon and so vizhi's LR will be actually scamed by him.Coz LR can not be refunded at all.
