Raiper341 based on my own experience by doing what you saying, only profit youl gonna make is getting your account closed by google, by having low quality content apps! its pointless into helping other people, trying to raise a community around your main games, with others peoples free advertising games, its a no win situation for you, and for the other developer he is going to win as much money he can by marketing his own app, and by using your existing followers from google play... unless you can rebuild his APK somehow and insert your own tracking download and install script so you can get some share from google play.. its pointless! anyway ... all people are free to open an account on google play if they pay the 1 time fee of 25 usd, that was the price when i bought it 1 year ago!
