There’s a new plugin at MooKitty by the name of Kitten’s Friendly Comments. Its a sort of whitelist that will check the eMail address of the comment poster against the eMails of past comments. If an eMail had been approved earlier, the comment with that eMail will be approved otherwise it’ll be set for author moderation. Seems like a good plugin. It also has a provision for adding eMails of past comments to SPAM words, which means that comments by these eMails would be set for moderation even if comments from that eMail were approved in past. 😀
Well, I think that its a good plugin, & its available for free here. 😉
