How to stop comment spam on your WordPress website
The following are different solutions to stop comment spam on your WordPress website.
1.Reduce the number of links allowed per comment post
Most comment spam is designed to add links in the comment section on your website and trick people into clicking on the links. One way to stop spam is to have fewer links in your comments. Legitimate visitors will also be prevented from posting many links, but slowing down the spammers can be worth that potential inconvenience.
From the WordPress dashboard, you can navigate to Settings → Discussion. Scroll down to the section Comment Moderation, it’s 5 section down:
In this option you can decide how many links will be permitted in a comment before it is flagged for moderation. You also reduce the number to zero if you want to require moderation for any comment with links
2. Create a list of ‘blacklisted’ words
A lot of spam comments contain a lot of recognizable keywords. This makes it easier to spot them appearing on your website. In WordPress you can create a ‘blacklist’ of words, and your site will flag any comments containing these words. You can also add URL, Ip address into this box too.
To create this for your WordPress website ‘Settings → Discussion and then find the ‘Comment Blacklist’ section:
Here, you can enter your list of words. When any comment is posted that contains one of those words, it will be sent to the trash. When using this feature it’s important to choose the words in your blacklist carefully, so you don’t delete comments by legitimate posters.
3. Restrict comment privileges to registered users
The goal of most spammers is to post on as many pages and sites as possible. The challenging you make it for them to add their comments to your site they will move onto the next site.
