Currently it seems like we start to have a KYC abuse, we see this term everywhere and for nothing.
It seems fair to follow a KYC process when you need to invest, so it's justified as they receive money from others parties, but for bounties or airdrops, it's just a steal of personal information. Be careful because some projects could be just a scam to steal personal informations, and if someone use your identity, sometimes, it can take years to recover from it, if the thief use it to make credits....
Just imagine if someone offers you a sampling of your favorite soda brand and request a copy of your ID card, your name, adress, phone number, will you accept ?
We shouldn't care if someone make multi accounts for bounties, because if he wants to be rewarded twice, he will have to work twice more, so well, being paid twice isn't a crime.
That is my sentiment as well. if someone has multiple accounts then he/she is doing the work multiple times hence the need for greater payment. Maybe because that person is an efficient individual and can handle multiple work loads all at the same time through skill and proper time management. I ask of you guys, how many e-mails have you created or used in your lifetime?how about social media accounts?we are going into crypto to move forward, why go back to the dark ages?these information that they are gathering is their tool for them to control society. Look at banks, you need to provide all sorts of documents before they accommodate your deposit for safe keeping, but we all know that our deposits are being used by banks to invest in other markets and gain money through it. so no to kyc.
Doing what for free twitter followers? Bounty, KYC? I did´t get you, sorry
