No, this is a "Guaranteed" giveaway, therefore it's definitely for SQR

Okay, this is an error on my part. I didn't realize that this giveaway was guaranteed, which affects my reply to the next quote.
When you start a non-guaranteed giveaway, you must provide a valid link to the Steam store page for the game to be given away. Since de-listed games (games that Steam yanked from their market) have no Steam store page, they are not allowed to be given away through IndieGala giveaways.
However, because this giveaway was guaranteed, it's allowed because the game key was obtained while the game was available through the Indiegala system (whether it be the IndieGala store, or an Indiegala bundle). This is the only exception where it's allowed to give away de-listed games.
So thank you
@curtainferno for the correction so I may improve my vigilance over the giveaways section.
