Empty datasets reveal zero patterns in call origins or behaviors, underscoring the need for vigilance with unidentified numbers. Without user reports, no specific threats emerge, but general privacy risks persist from unsolicited contacts. Block unknown callers proactively, enable spam filters on devices, and verify any callbacks through official channels. Report suspicious activity to authorities like the FCC to contribute to broader protections. Stay informed via trusted sources on evolving scam tactics, and consider apps that screen calls for added security. This approach minimizes exposure without overreacting to silence in the data.
