DownloadDir is a (pretty dumb) scammer.
Sold BTC for paypal to myself and at least 2 others in this thread https://bitcointalk.org/index.php?topic=156924.0
BTC never arrived at 1st he claimed it was because he/she/it sent them from Silkroad (and provided these screenshots http://gyazo.com/c158d3965b94b26e6adbf3a3f6f1fe51 & http://gyazo.com/d8928a8b54873a42aa020f83c853817c ) and it takes longer. He then vanished from communication. Its now over twelve hours since he claims to have sent.
