Not filter spam but just asking to moderate

I used Askimet for a long time. It filters very accurate, but the point is it has no options like forbid comments in Russian. Then I have to review all the spam again and again. This is tedious.
Installed the WPBruiser and hope it will help filter spam better than Askimet.
But it is not. The plugin just send emails asking you to moderate comments. So at this point, I think the plugin is worse than Askimet.

On the good point, it blocks some brute force attack, before that I thought the plugin did not work.
