This isn't the best cheating thing I've done, but it was HUGE to me at the time.

So, I was guessing security questions for neopets-related named gmail accounts around 2 years ago. I get onto one and there's an empty account. I log on and it's empty except... the bank account has 10 million neopoints! I started hyperventilating and my mom went in and checked on me, lol. I was 11 I think. Anyway, now that I think of it, it was probably someone's shell. If you owned the shell "nullspace", I'm sorry :C

How about you guys?
