Hey shoppa, I stumbled on this post, and looked into it for you.
It looks like you created two giveaways, one for 10 Second Ninja, and another for Watch Dogs. Both of these were private giveaways, and they each had a single entry from the same user. This user registered a couple of minutes after your first giveaway was created and won both gifts, but has neither redeemed on their Steam account.
This looks suspicious to the staff, because we have users that create private giveaways with fake gifts, and then ask their friends to mark them as received. However, I'm not say that's the case here. You said you shared the private giveaways on a forum, so it's likely the user registered and entered the giveaways after seeing your link.
If you can, just reply to the ticket with the forum post where you shared the giveaways, and I'll get you unsuspended asap.
Thanks!
