I'm publishing an app on the Android Market which has an ad in it. I've also been keeping the app's source in a public github repository. In the app, I have the line:
ads:adUnitId="MY_AD_UNIT_ID"
where MY_AD_UNIT_ID is my actual publisher ID. Is there anything malicious anyone could do with my publisher ID? Is there any reason I would want to keep this secret?
