All bloggers have to deal with spam at some point. You can’t stop spammers all the time, but there are many things you can do to keep them from hurting your community. Spam Master happens to be a cool plugin that helps you keep spammers at bay. It blocks new user registrations and comments by spammers to save you time. It uses thousands of known spam emails, domains, IPs, and words to stop spammers.
Spam Master protects WordPress from user registrations by bots and human spammers. It also protects WordPress comments. The plugin checks for e-mails, domains, IP addresses, and words. You do have the option to customize the message that is shown to blocked users. You can also add your own entries to take your spam protection system to the next level. Users can also see stats and useful information on blocked registrations.
Spam Master is fairly easy to use and could help you better combat spammers. It is free to try but to get the most out of it, you will have to get a premium account.
