Anti-Splog measures b4 I installed plugin

Hey guys,
Prior to installing anti-splog I had taken many measures to prevent splogs. One being the ever popular renaming of wp-signup.php to something less obvious, in my case it's newacct.php throughout the site. Since the plugin renames wp-signup.php dynamically do I need to revert back to the old filename, wp-signup.php or should I keep it as is?

Cheers,
Ricky
