[Plugin: WP-SpamFree Anti-Spam] WPMU sitewide activation is not working

Hello,
When using this wp-spamfree plugin for wpmu, activate as sitewide, it’s not working.

Spams keep coming in, plus even I try to activate the second non-java method, I still see spams coming in. Sign up new users and testing, and saw that it’s not working still.

How to fix wp-spamfree to work with all users/accounts on WordPress MU?

I’m using wpmu 2.7.1. The latest wp-spamfree too. As now wp-spamfree only works for individual wpmu user, this means each user has to activate this plugin manually.

Thanks..
