Bulk mailbox creation as attack infrastructure

Every entry restates the abuse or fraud objective described in one named public source — press reporting, court filings, law-enforcement announcements, platform disclosures, security-vendor research or academic studies — and links straight to it. Nothing is inferred from other platforms, and no method, tooling or access route is described. Objectives documented in evidence are not a measure of how often they succeed.
