Comment spam and registration spam remain a large problem for WordPress users. It is not uncommon for some WordPress websites to receive hundreds or even thousands of comments every week.
This level of spam can damage your reputation with readers and commentators if you fail to tackle it. It is therefore important to face spammers head on and thwart their attempts at spamming your website.
Thankfully, tackling spammers does not need to be a time consuming endeavor. If you configure your WordPress website correctly, and install a good anti-spam plugin, you can eliminate the vast majority of spam from your website.
