I am confused: this seems like a separate issue. If you post an ad for a Page, you get charged if the user Like's it, even if they don't really pay much attention. However, the whole point of a Page is to be able to target users with content later: those Like's from people trying to train their newsfeed are actually the very people you were trying to find. Meanwhile, for ads that have a normal landing page, you should be charged only if the user actually clicks the link in the ad and is taken to the destination: that is not a "Like" action.
