The Disqus for WordPress plugin lets site owners and developers easily add Disqus to their sites, replacing the default WordPress comment system. Disqus installs in minutes and automatically imports your existing comments. -WordPress Plugin Directory
By default, after having integrated Disqus with WordPress, affiliate linking is enabled. You can easily disable affiliate linking by
- Login to your Disqus Account
- Click on Admin on top right
- Click on Settings
- From the left Sidebar, click on Advanced
- Remove tick-mark from Automatically append merchant codes to product links on your site.
- Click Save
- Done
Note that disabling will only apply to links outside of the Disqus comment iframe (within your website content). Affiliate linking cannot be disabled for links posted within Disqus comments. -Disqus Help Article
