学校是否都主张让自己申请不用中介否则可能拒绝申请材料？

卷卷aUID: 3898296

LSE的申请页面有写以下的话，其他学校应该也有写，那让中介申请会对申请结果有影响吗？

LSE expects all applicants to complete their application materials without the use of:
paid agents
credentials services
other paid professional assistance
The use of such services may lead to the rejection of application materials, the revocation of an admissions offer, cancellation of admission, or involuntary withdrawal from the university.

想知道学校是通过什么痕迹判断是否使用中介的呢？过于类似模板的文书？
