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.
That's the most tragic result when people do participate on any Cryptocurrency related like ICOs and bounties that requires KYC.
Personal identity will be required by the company to every participants and that would lead into trouble in the future and that's what I am thinking before and now they're happening.
I think organizers shouldn't require personal information on regulating ICOs because it will hinder them to reach their soft and hard caps because most investors today aren't really into KYCs
