Googling his name brings up this article as the third result. Someone in whatever college he has been accepted to will surely discover and spread rumors, which he can’t really defend against because all the evidence supports that he did it. If he tries to publish anything, people will see his name and immediately question its legitimacy. If he gets an offer and the employer finds out they may rescind it because they can’t trust him.

Maybe he won’t outright get his admission rescinded, but I can’t see how a prestigious college is worth more than an intact reputation (I’m sure that without this award he still would’ve been accepted to a great community college at worst, and with his research internship assuming good AP scores, he may have even got into his top choice).
