⚡ Banhammer: Protect your site against enemy hordes!
</blockquote>
Banhammer gives you full control over who and what may access your site. Visit the Armory to monitor traffic and review suspicious visitors. If you find some user or bot that is causing problems, you can ban them with a click. Or, if you just want to keep an eye on someone, you can flag them with a warning. Any banned users will be denied access to your site, until you restore access via the Tower. Check out the video and screenshots to get a better idea of how it works.

Privacy
User Data: Banhammer collects user data to “do its thing”. The collected data is temporary and automatically deleted every day, or at whatever time interval is specified in the plugin settings. The only time that any data is “remembered” is when you ban something. For each person/thing that you ban, the plugin stores either the IP address OR the username (never both). At any time, all saved data may be deleted permanently via the plugin settings and Armory Tools.
Cookies: Banhammer does not set any cookies for regular visitors, but does set a few simple cookies for admin-level users. These simple cookies enable dope effects and interactivity in the Armory and Tower UI. But no cookies are set or used for any other visitor/user or purpose.
Services: Banhammer uses a free lookup service for GeoIP information. This happens only for admin-level users when they are viewing data in the Armory or Tower. No other third-party services are used by this plugin.

Banhammer – Monitor Site Traffic, Block Bad Users and Bots

Because the info on this plugin says nothing about it, I feel obligated to do so: 
It does NOT work on MultiSite, unfortunately :-( 

It looked very promising, the author announcing it on his own website with the words "waaay too much fun". And I can imagine it is indeed, but not if you are running a multisite installation and find out your site has had no protection whatsoever, since installing this plugin. 

So, in this case: no, it's not waaaay too much fun, unfortunately...

Does not work on MultiSite!

Monitor traffic and ban unwanted visitors. Block any user or IP address so they can't access your site.
