I need a website that can randomly select a user signed up to win prizes and be able to check for duplicate registries and blacklist them from the drawing. Basically a system that defends against cheating by having multiple submissions. If twitter can be connected somehow even better since users will need register for the site and for twitter.
Need a simple website with a raffle option. 20j left
