Some issue I've found after using the product

Entries are reset when refreshing the Giveaway's page: Recent Ken’s Promo I had this experience. Now im not sure i entered the giveaway or not

Seems like to easy for user to do a task and get done with that task without any verification. (so it’s easy to cheat the system)

The “Share with friends and earn extra” just not working. (since everytime i refresh the page my entries are reset)
