AdSense Referrals Now Have 90 Day Limit
Google has quietly updated their referral program to have a 90 day time limit. If someone signs up for an AdSense account using one of your referral links, you will now only get the $100 bonus of they earn the $100 within 90 days. This makes the referral program, which had already been criticized of not paying out very much, even less attractive. Many new publisher will spend the first 90 days just experimenting with Google ads, so the chances of getting the bonus now seems slim.
The worst thing about this is that Google did not make any kind of official announcement. They simply updated the fine print on the referral button code page to reflect the new 90 day limit.
