In a perfect world, none of us would have to deal with hackers and spammers on our sites. But as soon as your site gets popular, people will come out of the woodwork to attack your website. WP-Blacklister is a plugin that helps you handle those attacks. It provides you with a set of tools to block bad URLs, emails, and IP addresses to reduce the number of attacks on your site.
The plugin is pretty simple to use. It keeps track of the IPs, emails, and URLs of people who have left spam comments on your site. Webmasters can use this information to completely ban certain people from their websites (using .htaccess or Nginx.conf files). Of course, there are other ways of doing this. WP-Blacklister makes the process easier though.
WP Blacklister does not have many options. But does what it promises well. Nice tool to use if you have trouble getting a handle on spammers attacking your site.
