Perfect Plugin - it blocks Botnets. And other things too. I have a Private Galleries area on my site and once the "blocker" is activated no-one can sign in to these Private Galleries either?
I'm using this plugin with Wordfence without apparent conflict.
Also using the whitelist feature without any problems. I'm on (3) dynamic IP address ranges.
Five stars even though I'd also like to extend the 5 hour blocking limit to 24 or more.
