所有用黑名单内的邮箱注册的都会提示One of our mostly harmless robots seems to think you are not a human，包括californiacolleges.edu，官方刚给我邮件证实：“our automated tools identified an .edu email domain not associated with or issued by a school or university being used for academic discounts“，"The email address that caused your account to be flagged was *@californiacolleges.edu"

我github账号里面一个是自己学校的邮箱（主邮箱），还有一个是californiacolleges.edu（备用的，有时也用来扯扯淡），申请的时候用的是自己学校的邮箱，结果还是给取消了优惠，联系了客服说明情况，让我移除californiacolleges.edu，然后再次申请，现在已经恢复
