But I've lost trust in this guy after reading his blog posts and especially the phone call he published.
The only reason I can think of why the phone call took over 7 minutes is because he wanted to record it and publish it. Really. If you summarize the phone call. It's basically Apple asking him to publish that his account was indeed linked with the fraud account (not even that he's the one who committed the fraud) and he's working with Apple to resolve it, and rest is this dash guy complaining on and on which is completely unnecessary since Apple already knows that and is saying they understand and want to work with him to "make this right" (The Apple guy literally said "make this right").
Also it is very hard to believe at this point that a "relative" did all this. If I--or any normal person--was in the same situation (I am paying for a relative's developer account with my own credit card with my device and turns out that the relative is committing a fraud), my first reaction would NOT be telling Apple "This has nothing to do with me", but "I had no idea, I am still pissed that you guys didn't notify me, but I also understand your position and will talk to my relative to make sure this doesn't happen. After all, I am the one funding this fraud regardless of whether I was aware or not aware.")
