My argument is, this attention wouldn't even be here had he just kept quiet.
I don't think he was clever enough to have foresight that a) this would get this much attention, and b) he would need to deflect said attention by fabricating an elaborate hoax.
The guy was simply wanting to brag about what he did in the excitement of him actually pulling it off. I think this is much more believable than him fabricating this story.
One issue to be thought of is if he tells how he hacked the accounts, it would become difficult for him to hack some other accounts in the future. But I have found out that he has a habit of giving out advice to people. I have done some searching and found out (hopefully) who he is.
