Shawn asked me if I was aware of this thread at his forum named New referrals adsense ruls? where a member points out that AdSense has added a little line to the TOS that includes a phrase "within 90 days of sign-up." Now, everyone I ask, and every place I look, I can not find the 90 day requirement. That is a big deal. So on November 4, 2005, when the AdSense Referral Program Launched, it did not have the 90 clause, as far as I know.
Of course you can imagine how upsetting this is to those who sent AdSense tons of referrals, and how those will expire.
