Because i participated in a few giveaways where we guessed the winner of a sport event and just realized that people can cheat by updating the pick last second or just after the result comes out

Oh right, I see... have you a link to it?

sorry, no. it was few weeks ago . No one cheated, just i thought there was a possibility , and since you develop programs i thought you can make that. thanks

I'll bear it in mind... so if it fits with something similar I'm doing, I can add it.
