For your private keys to be safe is not the work of myetherwallet or any other wallets provider, it is your duty to keep your wallet private keys safe. I saw a guy that fill a bounty Google Doc form with his private key and I was surprised why instead of putting public keys he put his private keys and if I am a bad person I will move his tokens and ethereum in his wallet.
One needs to utmost take care of their private keys and save or store it in the offline mode. Either right it down and keep it where only you can access it and not shared with anyone obviously. Even while sending or mentioning address you need to be sure that you are not sending private keys and even if somebody asking you due to any reason it is an alert of scam.
