While your actions may be well intended you have ventured into a grey area. The military services are currently struggling with how to address certain events that occur within the social media realm. These type of situations need to be addressed in concert with the commander and the JAG office. Not at the mid-grade leadership level. This issue may require a policy decision by the command.
I would encourage you to bring this to the attention of your chain of command. It may be necessary to provide them with proof in the form of a screenshot or other similar means.
