Well if you have read one forum rule.
7. No begging.
Well, it looks like someone has entered the wrong address here, or maybe you have a certain relationship with the owner of the account, or maybe someone who is kind enough to give some Ethereum to you, but clearly you might be lucky, so use Ethereum as good as possible
He's lucky and this can be the possibilities.
Your lucky to be part of those people that received distributed ETH, maybe he's just a good samaritan. The time interval for those OUTs aren't too far from each other so if there's no real transaction involved he just sent it voluntarily.
