The author of the blog post is unknown, they have not provided any of their details, so we cannot even respond to the allegations.
If one is being accused of any wrongdoing, it is normal that the accused is provided an opportunity to explain. We are not able to do so, as the cowardly author of the defamatory blog post is hiding behind an anonymous screen name.
