Increase of the advertiser-referral bonus!
We have doubled the bonus for referring new advertisers to 10%!
This enables you to earn more money than before, and our recent cut in our advertising prices makes it even easier for you to refer new advertisers!
We strongly recommend you to refer as many advertisers as possible, you will not only earn a huge amount of points for it, you will also increase our advertising revenues, which means higher payout-rate and more money for all of us!
