It's plain stupidity, private keys are called Private keys for a reason, I don't know why people refuse to be smart this days, I've never click on any link for something I don't work for or something I'm not expecting, there is nothing that can make me share my private key with anybody....

Even if satoshi nakamoto is a well known person and he contact me through video call and I'm 100% sure it's him and he ask for my private key to my BTC wallet I will block him
