Over time, shared system users build belief relationships with the financial account they track. This hope can expand for a collection of reason. For example, the user force identifies the title-holder of the trust account in being or the relation might be operated by an entity commonly considered as trust worthy, such as a popular news agency.

These incidents show that it is critical for a social network to be able to reliably detect and block messages that have not been authored by an account’s legitimate owner.
