We regulary receive spam reviews in Magento, but manually approve/decline reviews so it does not make any harm - other than a few seconds extra work.
But I wonder.. all spam posts are always (without exceptions) related to the same product. I tried to change URL to this product a while ago, but no difference. I know I can delete and create it as a new item.. but I'm a bit querious on why this product only is affected. Can anyone explain why?
