This is share wiki pedia in term of KYC.
Know your customer (alternatively know your client or 'KYC') is the process of a business verifying the identity of its clients and assessing potential risks of illegal intentions for the business relationship. The term is also used to refer to the bank regulations and anti-money laundering regulations which govern these activities. Know your customer processes are also employed by companies of all sizes for the purpose of ensuring their proposed agents, consultants, or distributors are anti-bribery compliant. Banks, insurers and export creditors are increasingly demanding that customers provide detailed anti-corruption due diligence information.
But this should only applies for the people who invested on a certain ICO because they are the ones who launched their money for this investment, which is related to the anti-money laundering regulations, but if it is only about social media bounties, signature campaigns, I guess it is not necessary to be apply, we are just bounty hunters that are just participating through this forum and even in social media without putting up any big capital at all for a certain company to be wary about our personal backgrounds.
Because it is not safe for someone to always gives his real identity in the internet, we don't even know them if we could really trust them with our personal information, they might use it on bad things like faking their identity using ours.
