刚好看到这篇，就稍微回复一下
很多人也许怕麻烦
怕面对毕业后多年不见的教授
怕教授迟迟不上传 又不敢催教授
有些人索性就干脆自己写(另一种状况是被教授逼着自己写)
然后，自己收验证网址，自己签名，自己上传
但千万别小看你申请的学校
最有名的例子，莫过于前几年
有人帮自己的教授们上传推荐信
然后收到以下学校的回复
I have begun a review of your application and noticed that the recommendation
letters submitted by XXX and XXX were submitted on the same physical computer
that you may have used multiple times. Could you provide some background
information on why this may have occurred?
最后这个人被学校拒绝了......
还是不要心存侥幸比较好
