Interfolio does have multiple checks in place that monitor delivery destinations for every packet that we send. Some of these checks are technological, while others are manual. We take the confidentiality of documents very seriously and go out of our way to ensure that documents are going to appropriate destinations.
Also, courtesy of our terms of service: "In addition, you are responsible for all activity occurring under your User account that is in violation of or in conflict with any applicable rules, regulations, policies or guidelines in force at your institution, including but not limited to, academic integrity or honor codes and acceptable use policies."
Thanks!
