What do i do if i won a giveaway and its fake?

Report the user :)
They achieve nothing. They just think they do. The problem is, they don't get contributor value until you confirm. After a week, you can mark it as not received. But you can report them at any point.

Same thing happend to me. Report him and give him negative feedback after one week.

1) if the giveaway creator does not deliver the game, you can mark it as "not received" after 7 days and then move on =)

2) they achieve nothing from making fake giveaways

Answer: Don't start 2 threads, 1 is enough.

Cool thanks!

Report and mark as not received. Bout all you can do

Report and send SWAT to his house.

mark as not received and forget it.

You stop, drop and roll

The creator has a week to deliver. So if its indeed fake, you need to wait until his deliver period ends, then just mark as not received. No need to report (i think), SG staff will do the rest
