By default WordPress allows readers to write comments under the posts. Comments are a great way to create an interaction with your readers and get feedback from them. But unfortunately, WordPress comments are constantly subject to spam messages.
Spam comments are mostly sent by automatic software and contains links that lead to the attackers own pages. Even non-popular WordPress blogs can get thousands of spam comments every day.

Step 2 – Using Google ReCaptcha for WordPress Spam Comment Blocking
To prevent the spam commenting on our block the second method is ReCaptcha. This system automatically creates a visually composed image of characters and demands the user to enter the characters in the corresponding field to prove that they are human or not. ReCaptcha is a great way to block the commands which are created by a software. Unfortunately, it is not effective to stop the manual spam; so for that we first set up the Akismet plugin.

5. On target screen first of all you should save your blog address. Enter your domain name in the Label and Domains fields, and then click the Register button.
6. New Site and Secret keys will be created for your blog.
7. Copy the two keys and go back to the settings section of the ReCaptcha plugin.
8. Paste the keys into the relevant fields and click the Save Changes button.
