It is not scamming and Capting will sort it out.
Doing a giveaway is gifting items/money to a random individual who has entered it. And therefore the scamming rule does not apply to it. The scamming rule clearly states that:
It is not considered a scam unless money or items are lost or received. Except in the case of agreed upon coinflips, dice rolls or minigames.
A giveaway is neither one of them. Therefore it's not considered a scam.
