Blog HELP! Blog spam - I'm getting 100 posts a day
 

URGENT!

In the last week I've started getting around 100 spam blog posts per day.

What can I do to stop this? Deleting them is taking up lots of time every day.

Even if I delete the user, their post remains in the admin panel under "View Blog Entries". I have to delete them individually (there's no mass delete tool). It is taking up hours of my time. I have tried everything to stop spamers registering in my forum but it seems to have no effect.
