AdSense adds a 90-day time limit on AdSense referrals

I’m not using this program, and probably just as well. Jensense reports that Google have quietly added a new term to all AdSense referrals generated by a publisher, a 90-day time limit on that referral, meaning a referred publisher must earn the $100 within the first 90 days, before the referring publisher is eligible to earn that $100 for a completed AdSense referral. Let’s face it, most people signing up to Adsense for the first time aren’t going to make this (and if they were they’d 99% most likely already be using Adsense).
