Hey thanks for letting me know of the bugs. Presently I am not disallowing repeated submissions. Earlier submitting a review required you to be logged in. However, I thought that might put off users who didnt want to go to the hassle of signing up with an account. But yes that is something I need to solve. Also, you are correct - there is not much user input validation. So lots of work that needs to be done.
