You don't get the point, even if it was just the manager of a certain bounty, still, you don't know him personally, my question will be, would you trust your newly neighbor to take care of you son? I guess not, you don't know what he will do your son when you are not around, same goes to your personal information that is being exposed whenever you are submitting it in any projects that requires KYC.
Wait until it backfired to you, let's just hope nothing's worst gonna happen.
It is beyond me why this concept seems so difficult to grasp, if I have to go through KYC because a bank asks me at least in the case they reveal my information against the terms established in the contract I have some legal ways to get some compensation, when you give your information to icos they can use your information as they like and in the case they sell it there is nothing you can do because most likely they are in a different country and sometimes they did not even revealed their identity.
