This would be sort of humorous if it wasn't so depressing.
I found a number of Typepad blogs which are simply shock full of spam. It appears that the blog submission address has probably ended up on spammers' mailing lists, and so the spam goes directly to the blog.
Here's a Google search which demonstrates this. It appears that these blogs are basically on autopilot, and only the spammers have been posting to them lately.
So I tried to contact Typepad support, which goes to the mothership, Six Apart. I was too lazy to sign in and I wasn't reporting this as a paying customer of theirs anyway. Well, that didn't turn out so good. I have now received five substantially identical emails with basically no intelligent content at all.
Thank you for allowing us to be of service to you.

There is no indication of what they are responding to (what if I had submitted multiple support requests?) and no indication of what sort of response they are soliciting, in spite of the phrase "below is a summary of your request and our response". I replied with a question about what they need from me and what the status of the problem is, only to receive another one of these, etc. Finally I just said forget it (to which I received the reply you see above).
So Melanie and Kymberlie, if you see this; hi, that's you in that picture. (Sorry, couldn't resist.)
Seriously, I'm hoping their paid support is better. (My experience is that it is.)
