Reffered...

Yeah, this just wouldn't work. If I really wanted, I would just refer a bunch of members on difference computers, post 15 times, then never touch it again. That contest has too many leak in it. That is probably how you are getting so many hits. Its the same person every 1,000...

And yes, it is definitely very easy to get on different IPs and do this. Finding out people that are cheating this would or at least could be very difficult. I don't like the idea.
