Ive recently been posting alot of items in the exchange sections. With this, Ive been getting alot of PM's asking for pictures, making offers and offering trade. Which is all great, mostly. But lately Ive been getting loads of time wasters. Not sure what they have in mind. Asking for pictures, or more details on other items etc. Only never to reply. or "keep them for me" then nothing or later reply saying they cant afford, or their gran has died.. Admittingly, most users are new users. Whats the deal?
