How do I stop my campaign from auto-posting to social media?

Hello, I just posted a campaign and was very clear and specific that I could NOT use any social media outlets. I was very careful not to add any facebook, twitter, linked or any other social media accounts. I wanted to use the "view as webmail" feature. However, when I went live, and clicked on the browser, there was a banner from Constant Contact with clickable links to share on FB and twitter (again, clear I could not use any social media because I am running a campaign and the rules said NO SOCIAL MEDIA). I am now afraid I will be disqualified. Why would constant contact not warn me about this or give me the ability to disable? Where is the information to disable social media anyway???
