I am sure all adsense publisher would get this email about the changes. Basically the bonuses for referring new publisher reduced. I would think that the cruicial benefit which is removed is that you get $5 when your referral earned $5 within 180days. This is because it is hard, real hard to get $100 in adsense within 180days. Unless the referral bought a existing website to start off.
On February, countries in North America, Latin America and Japan will enjoy only $100 for when referral gets $100 within 180 days. While other countries will no long get anything for referral.
I think the reason is that those countries listed above are those who manage to perform well and most probably purchases online is highest, which allows online advertising be effective.
GAdsense manage his accounts as G wants!
No way, what can we do?
only get it off?
