I thought all my Christmases had come at once tonight when I found an extra 100 comments had been added to the weblog during the day. But, sadly, they were all spam.
MoveableType isn't too bad at handling spam as it allows the banning of specific IP addresses, so, theoretically, spam from these people won't turn up again. This has happened from time to time where I've had one or two spam comments during any one particular day. But 100 seems like a concerted attack. I've worked my way through them now and deleted all the comments I can. I'm just not sure if this is as far as it goes. Therefore I would suggest, if you intend to leave a comment, don't leave an email address. I don't think the spam robots are smart enough to pick them up but it is better to be safe rather than sorry.
