I am pondering the same question as cynthiablue.
I have been running my blog for half a year without any spam. For the entire time, only registered users are allowed to post comments with me being the only registered user. When the spamming started two days ago I completely turned off the comment function in the options section and upgraded from WP 2.0 to 2.0.2, yet the spamming still persists.
How is it possible spam keeps getting into my moderating queue when comments are turned off and noone is a registered user except my admin profile?
