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.

There are currently no truly self-sovereign ID solutions available and our partnerships with Edinburgh Napier University is geared towards this goal. We also do not hold any information on the users - the only data is stored on the users apps. The way we integrate with merchants is also different as we don't require them to lock into using Blockpass for set times or put any other conditions on them. We also offer discounts on the KYC for merchants and we are implementing a reward system that will encourage merchants to verify further certifications.
In the long run, we aren't simply providing a KYC solution. Blockpass' ultimate goal is to provide identity for humans, companies, devices and objects on an IoT level. The human aspect is simply the first part that we are implementing.
