So if you invest real money in the project this means that you should have trust in it. If you have no trust in it i would not invest my or my money in a project. On top of that giving an fake ID makes not the real owner of the account
That's right, fake KYC is only suitable for you to participate in bounty or airdrop. But if you use exchanges or take part in projects, I think you should use real KYC to avoid the trouble later.
