Dude... no one steals apps. If apps are on 3rd party stores published by some one else, i don't know why they are doing it but surely they do not have a lot of downloads and most probably they just want to grow that particular app store's traffic. But i guess you know better. Your solution clearly solves .. problems .. BTW this forum is almost dead and it's filled with crappy information and spam. You won't get any high-volume traffic here, obviously any sane developer with solid traffic will protect that and won't go this road. And for developers who even think about this, just so you know, you need some ways to get more INSTALLS, not ads.
I feel like i gave more value through my posts, freely, then you and your services. I will stop here.
