User Reporting of External Threats
Without preparation, users may misuse the reporting feature, leading to false reports and unnecessary investigations, which can overwhelm the admin team and distract from genuine threats.

Increased Admin Workload
The introduction of user-reported security submissions may lead to an increased workload for admins who must review and investigate reports, potentially causing delays in addressing actual security threats if not managed properly.
