此题的comment似乎跟老师讲的有点不同。老师的意思是Moddy didn't violate the Standard since she had given clear instructions to suggest against personal info publishing. 但是材料中comment的意思是，虽然Moody没有违反，但是"if she deleted the info at once, she would comply with Standard",这句话的潜台词是不是如果Moody没有及时删除客户信息，就违反的条款呢？所以就整个case而言，她是违反了还是没违反？谢谢！
