How does pin trading work?

I'm curious how this works. For example, on the forum section - http://www.sythe.org/forumdisplay.php?f=376

Why do people trade their accounts, some which are such a high level, for a few measly pins, when I see here, http://www.sythe.org/forumdisplay.php?f=321 sell their accounts for $100+. Why? And what is a pin<cards you get at target? from pay by phone>? Thanks ^^

 

some people cant get pins cos they're location or 19 numbers blocked etc

 

O____o Interesting... I don't see why they don't just sell their accounts for a crap load of money, and just buy the pins online for real money/paypal... So say I sell someone a pin for their account, I get their account for ever? No strings attached?

 

most people get pins... and recover their account back, if the deal seems too good to be true... don't do it .

 

Yeah, there either very desprate or scamming.
Only trade them if there VERY TRUSTED!

 

What Tony said, if it's too good to be true, it probably is. Other times, people just want to sell off an account that nobody really wants, so they don't care if they give it up, because it can get them a pin.
