This is nothing new. Scammers will take advantage of any situation to make money. There is a lot of stuff in the media people asking for money to help them escape the crisis. I have come across some on my facebook feed, pictures of women and children in distress. There is usually a writeup that they need money to save themselves. Anyone who falls for this scam has themselves to blame. I believe there is a official Ukraine Bitcoin address for donations if you're feeling generous.
