Unfortunately, we had to enforce the KYC requirement due to the fact that we have witnessed the participation of many bots and fake profiles (including repeating comments), which could have a negative impact on the bounty campaign. The purpose of the bounty campaign is to educate folks about the work that Virtual Rehab has conducted thus far, our achievements, our global awards, and recognition received thus far; along with what we plan to embark on accordingly.
Well, I must admit this is a good reason for a KYC for Bounty hunters, one I didn't think at. Of course it has a sense when announced at an early stage, which is what you have done. So that's fine. Other ICOs in the past had announced this requirement only after the campaign had ended, which I'd find unacceptable.
