There has been a huge influx of passport available for sale on the Dark Web.
Also have seen posts where people are being accused of double entry into ICO's because the scammers used their passport information prior to them getting signed up.
One reason why you should not participate on an ICO that has a KYC. This KYC doesn't really protect the customers but tey are compromising their personal identity. Even in Airdrop and bounty now have a KYC and I suggest don't ever join or participate in their program.
