the only way to interact on the website is to change from portrait orientation to landscape orientation. For whatever reason the ad then acts as it should and stays in the background as far as user interaction.

When in portrait orientation clicking on the “post” button still takes you to the ad, clicking in the body portion of the message post to type a message takes you to the ad, and pretty much just clicking anywhere takes you to the ad. Turn it to landscape and then you can click anywhere on the website without being directed to the ad.

I guess that is another insight too. It seems to only happen when you are on the page where you are replying or creating a post. This ad does not happen on the main message board when view the list of posts. These ads are only served on the page where you type replies or new posts.
