No one should ever send any hackers anything. The more you send the more they'll ask for. You know what will happen if she gets 100 ETH to them? They'll ask for another 500. That's just how they work. If she was real, she'd need to contact the authorities and deal with it another way.

The same goes for the Steem accounts. The only way to get them back is to recover, act fast, think fast, and move on. There's no negotiating with thieves.
