alfateam on "[Plugin: Wordfence Security] How to block/ban immediately if someone uses 'admin' as user ?"

I see 99% of hackers try to use 'admin' as user. I need to instantly block access to login for such tries. How can I do that ? I'am tier to see every morning 100 emails from Wordfance with admin' user trying to hack my site.
