You may also try if you have got this by login in to your dashboard. The first thing you will get is a green notice board that will inform you about the comment spam is enabled for your blog. If you have multiple blogs then it will be enabled for only one of you blogs (I expect).

I got this for the demo blog for Translator widget with flags. From the dashboard there is a clickable link to go to the New Comments page just on the left-hand side of the Settings tab.
On comments page you will find that there are tabs that will show the comments that are Published, comments that are Awaiting Moderation and Spam that will show the comments that are detected as spam.
