Horrid as I am, I can proudly say that I've been using the giftwrap scam whenever I get I chance (I usually keep it to people spamming 'wtb' on the trade channel). As soon as I found out about the exploit, I went out and 'sold' about 40 epics.. needless to say, I was 2000gp richer within a day, and I went on a 200gp spending spree right away. Soon enough, I got the 'this account has been temporarily suspended' message when logging on, and patiently waited out my three day time out...
When I got back on, I found that 1500+gp I had left over gone, along with the mount I had gotten for my 42 hunter. Instead of being discouraged from scamming again, I began to think about what I could do to keep this money... I could, of course, send it to a friend and ask him to hold it, promising him a share for his troubles, but greed overtook me. Then I checked my mail and found the auctions I had bought before my suspension still there: expensive toys. That gave me an idea, which I promptly tested...
500gp off a Krol Blade later, I sent 450 of it (in 50's, to escape detection by anti-farmer GM's) to an alt, and patiently awaited my suspension. Note: I did NOT open up the letters, I simply let them sit in that alt's mailbox. Again came the suspension, and again I waited it out... upon my return, I happily discovered the 450gp still in my alt's mailbox, and the 50 I had on me taken away.
The moral of the story: after a grand scam, mail the money in small amounts to an alt, and do not pick it up until after the suspension.
Enjoy
