Get Rid of Spam Using WordPress Settings
We can get rid of spam tweaking the settings within WordPress. Let’s explore the possible setting area where we can use the tricks to stop the spammers. For this please visit WordPress Dashboard & Go to
Settings > Discussion
1. Use of list of Blacklisted Words
Lots of comment contains the blacklisted words that are normally used by spammers. It is now easier to recognize and we can use those words and block them.
As it is said that, the Akismet Anti-spam plugin has already implemented those huge lists into the plugin so, it is not necessary to use the manual list but in case you need the list, you can find the huge list on Github. Check the Recommended Backlist Words.
- Go to
Settings > Discussion > Comment Blacklist
- Copy the list and paste it
- Save it.
2. Restrict the Comment Moderation
Use the option “Comment must be manually approved” so that you can approve comments one by one. It will be time-consuming for you to approve if your blog receives lots of comments.
3. Users must be registered
Another way to avoid spam comments is to tweak the settings available on the
Settings > Discussion. Turn on the settings “Users must be registered and logged in to comment“. This setting will make the spammer lazier than ever.
4. Disable Anonymous Comment
Turn on the settings “Comment author must fill out name and email” so that you can disable the Anonymous comments. It is pretty sure that you will prevent half of the spam comments on your website.
5. Close Comment After ‘X’ Days
You can also use the settings where you can automatically close the comments after certain days. Use the settings “Automatically close comments on articles older than X days“.
6. Hold a comment in the Queue
You can even hold a comment in the queue section if the comment contains the links. When a comment contains any of the listed words in its content, name, URL, email, or IP address it will hold the comment for the moderation.
