Thanks so much for writing WP Blacklist!
I (and probably others also) would find it really useful if you could add a few lines to WP Blacklist so that the blacklist MySQL table can have the same user-specified prefix as the other WP tables.
When installing WP, one has the option of changing the $table_prefix variable in wp-config.php to the prefix for the WP tables (e.g. $table_prefix = ‘wp_’;). It’s pretty easy to add something similar to WP Blacklist (instructions halfway down this page)
so it might be worth doing for future versions.
HTH!
