@MONKEYJUNK said is right the  site takes too long before it loads btw no it didn't loads, never redirect me to to the landing page it's just a black screen and continue to load. And as what others said 50% is very promising for referral commissions. And if you want to promote your site I guess signature campaign or social media campaign is much better. There's no so called free advertising here even it has 50% commission  for referrals.
