Disabling HTML comments in WordPress
Almost all comment spam left on your WordPress site will have some sort of HTML embedded within it such as links. In this article, we will show you how to disable HTML within comments on your WordPress site so that links can no longer be embedded.
Now that you are within your WordPress admin dashboard, hover over Plugins, then click on Add New.
On this page, you will see a search box. Search for the term Peter's Literal Comments, then click Search Plugins.
You should now be presented with your search results. As we have searched for the exact name of the plugin, you will see the plugin that you are looking for as the first result on the page. To install it, click the Install Now link.
WordPress will now automatically handle the download and installation of the literal comments plugin. Once complete, be sure to click the Activate Plugin link to ensure that it is up and running.
Because of the simplicity of this plugin, there is no additional configuration required to use it. Any WordPress comments placed within your site will now show as plain text instead of taking advantage of HTML.
