great plugin

Does what it’s supposed to do and blocks most of what I want it to block (proxies and VPN), the rest is blocked by other anti-spam measures.
An issue we had was quickly resolved (we hit the 1000 free api calls when there was increased spammer/hacker activity and all logins were blocked). The new option that sends an e-mail at 90% of our API allowance now alerts us in time and the plugin stops blocking when API calls are exhausted.

5 stars!
