The claim has attributed such information leakage to JamiiForums employees, mostly moderators who happen to have access to secret members information. This is one in a series of claims by its various members in the past, that there have been recurring incidences of their secret information disclosure to the third parties, warning current and future members to be more apprehensive in regard to the forum usage.
Possible primary causes of such confidential information leakage can be intentional (often made anonymously) or unintentional, mostly through system vulnerability, shared information using non-secure tools, deliberate disclosure by employees, employees accidentally sharing confidential information, information accidentally sent to wrong recipients or through phishing scams and social engineering.
