I’ve just deleted 691 spam comments, all but three of them identical – same name, same email address, same IP address, same (long and link-filled) body. I realize that spambots aren’t as intelligent as people, but surely they can avoid putting that many comments to the same place in less than 24 hours?
Not that I’d want them to be more intelligent, really. I’m just frustrated at how long it took to delete them all. Too bad WordPress couldn’t recognize all of the duplication.
