Please feel free to check it out, and give me your feedback, I've used it to delete at least a hundred pieces of comment spam in a matter of minutes. It's sorely lacking a search feature, but I hope to add it soon.
Thanks to any and all who may try it out. Be careful not to erase comments you intended to keep, there's no way to restore deleted comments. You can always add a few test comments to your blog and then delete them to see how it works.
