Block Top Spammers displays a list of your top spammers’ IP addresses, based on all comments in your database that are marked as spam. It also generates a blacklist for your
.htaccess file to block those spammers from your website entirely, thus taking load off the server. – You will need another plugin (like Akismet) to identify the spam.
PHP 5 and Apache required.

- edit blacklist (i.e. remove individual addresses, manually add addresses and/or subnets)

- Activate Block Top Spammers through the ‘Plugins’ menu in WordPress
- Make sure you have another plugin installed and activated to identify the spam (if you don’t, take a look at Akismet)
- Why do I have to edit .htaccess manually?
There’s two reasons for this:
- Allowing WordPress to write to
.htaccessas it does when you change the permalink structure would break many of my WordPress installations. Since I wrote this plugin first and foremost for my own use I would have never benefitted from this functionality.
- I actually had the plugin update
.htaccessautomatically. But then I blocked myself from my test site… Blocking an IP address through
.htaccessis quite a harsh measure. It doesn’t only prevent bots at that IP from posting comments, it prevents users who happen to use that same IP from accessing the blog. – I intend to automatically write to
.htaccessin a future release, with a few security mechanisms added…
- Allowing WordPress to write to
- Will the plugin work with older versions of WordPress?
It might. But I don’t support it!
I have written the plugin for and tested it with blogs running the 2.8 version of WordPress. It should probably work fine with any 2.7 version. With 2.6 the admin page looks odd and checking/unchecking all table rows is not working.
