Just an FYI. I've had to implement the word verification for messages. I'm sorry, I know it is a hassle. I am getting spammed so much, I think they have a program looking for blogs with no word verification, then come back and spam.
I will be trying the word verification and see if that doesn't reduce the spam. For now, I'll continue to monitor all posts as well, but if this works, I'll turn off the monitor comments.
