OK, I don’t know how real this all this, but if it is real, I don’t get the “let it be!” attitude.
So if I hack in to a computer and discover evidence of a crime (I wouldn’t BTW; and I can’t anyway because my skills aren’t that good), say evidence of murder/rape or even something more white-collar like stolen credit card numbers or corporate fraud, you people would say “let it be!” because I did something unethical to find that information? (and it doesn’t seem like the OP even did something unethical!) I’m sorry, but what type of warped moral reasoning is that?
As for adcoms, sure, they may discount stuff, but I wonder how properly. And (assuming that the OP is truthful), I indeed am curious how kids like that got in if it wasn’t because of fraud. Is it because the family is famous/powerful/rich instead?
I would say that the OP should be VERY careful, though. I think he’s already divulged too much info.
