Sed Lex

Block IP addresses which are suspicious and try to post on your blog spam comments.
This plugin need that you create an account on the Honey Pot Project (https://www.projecthoneypot.org, free api) or that you install the Spam Captcha plugin.
In addition, if you want to geolocate the spammers your may create an account on (http://ipinfodb.com/, free api). Thus, you may display a world map with the concentration of spammers.
Spammers may be blocked either by PHP based restrictions (i.e. WordPress generates a 403 page for such identified users) or by Apache based restriction (using Deny from in .htaccess file).
The Apache restriction is far more efficient when hundreds of hosts sent you spams in few minutes.

Automatic Ban IP

Block IP addresses which are suspicious and try to post on your blog spam comments.

windyjonas

If you want to block certain sections of the internet, companies, countries or specific users, you can specify the different IP addresses or IP blocks and where to send them and this plugin will take care of the rest.
<h3>Sample data</h3>
If you want to block for instance the <a href="http://www.gnuheter.com/creeper/ipblock" rel="nofollow ugc">IP-addresses of swedish authorities</a>, you can use the ranges below and instead show them the way to <a href="http://sv.wikipedia.org/wiki/Anti-Counterfeiting_Trade_Agreement" rel="nofollow ugc">the Wikipedia article about ACTA</a>. I’m not saying you should, I’m just saying you could, ok?
