Typekey

So blog comment spam, we all love it eh?

Typekey seems to be the way forward.

You now have to login using your typekey profile to leave a blog on the site, but once you have a login you can use it on any blog which uses typekey... and more and more will be doing so in the near future I think.

EDIT Typekey is only working on posts from here and onwards. Is there a way to make it cover all my previous posts, as that is where the comment spam is happening?
