You can send fake documents, of course, but I don't think it can work every time in every bounty company. But on the other hand, the procedure of KYC is not clear to me, because I do not understand how they check people. Are they watching everyone or maybe just someone randomly selected and that's it?
Because of your topic many campaign and company will be alert and i guess they'll look for more security and stuff. Just to protect the reputation of the certain company.
