Avoid, new precedent trying to be set, the more people the give in, then you'll have to give you info out for every single airdropped/bounty out there.
It's very dangerous for you to trust these non-reputable individuals with your information and for the future of cryptos as a whole, yet no one is discussing this.
You can blame Polymath for this, they don't want to work harder filter to filter puppets, so instead they want your ID.
Edit: There is probably nothing we can do to stop this, because the vast majority of people trying to do airdrops are very likely to hand over their info without a second thought. This has major repercussions, some of the worst repercussions we will see ever in crypto.
The best thing you can do if you're reading this, is to not give in to these new information whores, who are more than likely to flip your IDs on the darkweb for a profit.
I agree, it is not a good trend and I fear it will only become worse in the future. Pay attention by sending your ID documents to the ICOs!
This come to my mind lately. Because I've read an article about stealing of identity. Wherein people will stole your identity so that it will be use by other people for their terrorism or any other illegal activities. So as a bounty hunter, I am cautious on this kind of bounty campaign that requires KYC unless you are confident that their company is legit.
