I got the settings and i have just linked it with the WordPress Discussion setting “Disallowed Comment Keys” and the review form is working fine. exactly what I am looking for. Just a one question that if someone try to submit a spam comment then he is getting an error that “You can’t submit the review.” I want to edit the message and want a custom one. Please ignore the above thread. I want this that I wrote here.
Use the Settings > Strings page.
