Hey I'm glad you found the culprit to this obscene ad serving method. FYI, if you can, you should go back, and rate the app as 1 star in the market, and comment that the app uses AirPush, and then mark it as inappropriate and then when they ask why, say it is a malicious app. This is not the first time a developer has used this type of malicious advertising, and we need to send a strong message like the users in this article below states.
Google saw the huge outcry, and pulled the app, and with the overwhelmingly negative reviews of the app, even the developer finally saw the light. See below, and if you guys see someone in the forums complaining about notification bar spam, point them to this article and advise that they do the same. We need to stop this before it gets out of hand. See the article below:
