SCAM
In what conditions you are saying it scam. Do you have any proof that this user didn't paid anyone ?
Or this is just a Spam posting by a Newbie which is needed to be reported
As we can see he just make a fake giveaway and the winner 0.1 BTC is he's alt accounts.
So i think he's scammer and just want to boost positive trust with made giveaway.
Yeah I agree with you that he scammed for the special roll of 0.1 btc
But for your kind notice he have also paid that small amount to each one. So telling only a single word 'SCAM' do not seems to be a reasonable answer.
So, he have to also tell which part he saying is scam
Only scam doesn't make sense
