Although there are not articles, it doesn't surprise me at all that this is the case. People who have no idea how trustable an ICO is upload their passports without hesitating, which makes simply no sense to me. I'd be really careful about any personal information online.
The appearance of copies of passports on the Internet should finally stop the practice of ICO companies to require identification data and copies of passports to signatory campaign participants. I am absolutely sure that the presentation of such requirements is a personal initiative of ICO companies, because the regulatory bodies require that only those who invest their money in order to prevent money laundering received by criminal means pass the KYC test. Moreover, such a check is made after the end of the ICO for the purpose of not paying earned tokens to those who refuse to provide this data.
