A computer implemented method includes monitoring changes to an account accessible by a group of subscribers that form a social network. The changes to the account are compared to a normative base line to identify deviations from the normative base line. An alert is sent in response to deviations from the normative base line. The normative base line is defined by metadata gathered through an application program interface associated with the account, account entity data and a set of predefined rules.
