I think privacy comes apart, when money is involved. I saw this happening on this forum when Ripple was introduced. People only had to link with their Facebook account to get some FREE Ripple in the beginning. This immediately compromised most of these people and their account was linked to their real identity.

After Ripple, we saw a host of Bounties and Coin drops and services where they require your social media accounts and some ICOs even implemented some AML requirements to participate.

Is the few dollars really worth your privacy? Your greed might cost you more, when people use this information to track you or even to link you to your main coin hoard.
