i installed this plugin 4 days ago. and i found the performance of this plugin to be very poor.
this plugin has hardly blocked 20% of the spam registrations.
and moreover the "Blocked Email Domains:" feature does not work at all.
i have listed mail.ru and other domains in the field. but still there are spam registrations with mail.ru domain.
after installing the plugin there have been around 90 spam registrations and the plugins has managed to block just 26 out of them.
can the performance of this plugin be increased or this is the max i can get?
