There is no one-size-fits-all answer to this question, as the process of deleting all your Disqus comments will vary depending on the Disqus account you are using and the specific instructions that were provided to you when you created your account. However, some tips on how to delete all your Disqus comments include:
Log in to your Disqus account and click on the “Delete All Comments” button at the top of the page.
Disqus removes comments because they are not part of the commenting experience. Comments are a way for users to share their thoughts and ideas with other users, and Disqus does not want its users to have to leave comments to share their thoughts with other users.
An account killer is someone who, when they have access to a company’s account, takes steps to delete or limit the amount of activity that is allowed on that account.
