When adding a review to the catalog item (e.g. product, article, etc.) there is a code in place to prevent more than 1 review from single user within 1 hour. In some cases (see http://www.in-portal.com/forums/in-portal-modules/in-newz-news-management/bb_4259.html) this is not desired behavior, but at the same time disabling SPAM check to allow single user to add more then 1 comment per hour is not an option.
Solution
I'm proposing to:
- add new system setting called "SPAM protection mode" with:
- Use Captcha
- Limit Reviews/Rating Rate (see settings below)
- when the "Use Captcha" is selected, then Captcha control is added to review/rating form and unless correct Captcha code is entered nothing is submitted
- when "Limit Reviews/Rating Rate (see settings below)" is selected do what we do currently
