I was checking my email like 10 minutes ago and found this letter:
"I have your minifigure. If you want him back alive you'll bring 50,000 in unmarked Blokos to the warehouse off of the boulevard across from the car shop, you know which one I mean. If you notify the authorities you will never see him again."
This picture was attached:

It's hard to make out, but I can identify that it is indeed him. I logged into Blockland just to be sure and he was indeed gone.
I don't have that kind of money and I don't know what to do. Please help me, I want my minifig back. :(
