Let's put it like this. The burden of proof is on you. They have a game that will soon have 100,000 downloads, they are generating revenue. The 4.6 rating is high for ANY app with a similar amount of downloads. What do you have?? Words...in other words nothing.
This is no "scam" in the strict definition of the word. This is merely a "failure" to produce a revenue producing product. The games simply arent good. But it would still be incorrect to state this is a scam.
