@eif, mate you opened a giveaway and you sent the invite in 1 hour. This is a bad practice as most of the users didn't have the chance to see the thread and apply.
Standard practice is to keep the giveaway open for a couple of weeks (for good trackers even up to 4 weeks). Take your time, gather proofs from the applicants and decide who the best candidate is.

Just a heads up for any future giveaways
