Yeah why not, I suppose yeah it could end up on the dark web, never really thought about that,
But if its a good bounty return F it

Until one day you go on holiday, get arrested at an US airport and charged with card fraud, if you are lucky. If you are not lucky charges will be for terrorism, drug dealing or arms trading.
And while you try to prove that "some else used my documents" and "I am innocent" they will be thinking of how fabulous would you look in orange, inside an Egyptian prison.
But..yeah... bounty was good...so f*ck it.
That´s is a bit dramatic I think 
But anyway, the subject is really important. People are victims of identity thefts in real life - a guy I know got a credit card and ID stolen and he had to give long explanations about several hefty sums spent under his name on some betting sites. And I have heard of cases in which an email and ID were used to use a Paypal account.
Even one ICO that was legit, Experty, became "famous" for a identity leak. It´s a concern for many people, more if you have plenty of money.
