How spam callers actually get your number
Spam calls feel random, but Engadget's latest explainer shows how often the path to a stranger's inbox starts much earlier than most people expect. A phone number tends to spread through ordinary everyday habits rather than a single dramatic breach, which makes it easy to overlook. For anyone working in tech, security, or customer-facing roles, this is a useful reminder that user data hygiene is partly a behavior problem, not only a technical one. Product teams can make better privacy defaults, and individuals can adopt simple habits that limit how far their number travels. Understanding the origin of the problem is the first step toward solving it. What privacy habit do you think matters most for protecting a phone number?
