WordPress Plugin: June Comments Cleaner
For example, if your blog has a great number of visitors/commenters and you have selected the "Comment author must have a previously approved comment" option in your admin panel (Settings > Discussion) or you allow comments to be published as they're posted then nothing will stop a previously approved commenter in adding a hidden javascript code(could be ajax, redirects or very annoying popup windows) in his comments which will mess up your blog big time!
