Various embodiments described above can enable referral lists to be used in connection with distributed content to protect a referral infrastructure that is used with such content. In at least some embodiments, referral lists are protected using digital rights management (DRM) techniques. The DRM techniques can be used for a number of purposes including securely establishing a referring consumer, securely maintaining a chain of referring entities through distribution tracking, and maintaining control over the referral lists associated with distributed content. In at least some embodiments, DRM techniques are utilized to protect referral lists that are used in multi-level marketing networks.
