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!
In other words we should do more investigation before we submit KYC in some ICO's. We should more aware that this process is not safe because our identities will be use for some scam intentions. We should double check before we apply because its only for the safetiness for the sake of our personalities.
Soon this expectations will be also true and there is nothing we can do about it.
