Interesting article by Ruslan Kogan about the "ugly affiliate marketing scam". A few things,
1. Yeah, somehow +OzBargain
ranked #1 on "Kogan Voucher" on Google AU and also on the first page SERP of other related keywords.
2. Kogan is on DGM network in Australia currently paying 0.75% commission. Various cashback sites are rebating between 0.5-0.7%. However I don't recall the commission has ever been 5 or 10%.
3. Yes, I did apply to be an affiliate of Kogan on the DGM network, but got rejected pretty much straight away. They probably thought we are one of those ugly affiliate scam :) Interestingly cashback sites are approved, and I don't think they are the kind that "send in new visitors".
4. We are still sending them quite a bit of traffic & sales nevertheless :)
