either ur a pin hacker or ur spending a hell of alot of cash on pins it slike $10 a pin so u want 500m thats i think $5000 dollors real money. (not good at math). but gl anyways hope u dont get sued=)
EDIT: if u get pins free by "hacking" them i think u will get more then sued.
Wow, Good-luck. 97 million is quite alot of money, you should invest in something like a Mask or Santa Hats. They go up quite rapidly and you don't have to lift a finger. It's a good investment.
