He didn’t say you were begging. He said he would prefer begging (and rightly so).
If it had to be called anything, it would probably be ‘scam’. Paying $5 without having any guarantee that it isn’t a scam or that the app is even remotely hackable is crazy. Even more so when all there is to win is $25. That really makes no sense.
Also the “it’s a learning tool” argument makes little sense. If you are trying to learn from us, then why in the hell are we paying you for it?
Really want to learn? Put it up for free. Big chance you get free advice, which is quite a good deal considering what you would normally have to pay in a commercial setting for such services.
