We have used it extensively and have never seen an AD. That being said In-General ads are targeted based on the browsing history of your ip address. 🙂 Most filters that we have seen will block ads, and you should be using a filter regardless of whether you are using apps4flip or not (See the disclaimer on our website). We are not a rav hamachsir, nor do we pretend to be one. Visit geder, see what they can do for you, and be responsible.
