I know how you feel about such GA. But still it might land you on bad spot.

According to FAQ

• I think I spotted a fake giveaway, what should I do?

We try to allow all giveaways to run their course without judgement. An exception is when a giveaway creator enters a description that clearly states their giveaway is fake, or if the description illustrates a lack of understanding of how the giveaway system works. In those instances you can create a support ticket to inform us of the issue.

You should always refrain from writing comments which accuse users of posting fake giveaways, or question their integrity. It's important we show giveaway creators respect by allowing them time to follow-through with sending their gifts.
