KYC is important but it can be a pain to carry out and there's the worry that people will use your info as you've pointed out.
Check out Blockpass - we're working on a self-sovereign identity verification app which would give you the ability to 'anonymously' KYC. We're working with Edingburgh Napier University on Zero-Knowledge Proofs amongst other things to further this goal but we already have the first version of the app available on Google Play and the App Store.
