I know we can't save everyone, but you can protect yourself against phishing attacks by trusting in common sense. If an offer is too good to be true, there is definitely something to it and it should be questioned.
Looks like common sense is not so common. Otherwise there would not be so many hacked accounts. People should not give their wallet keys to others at all. And they should always double (or triple) check the website address, where they login to their Hive accounts.
