Signals You Should Keep Private
Look beyond obvious secrets like passwords. Calendar fragments in screenshots, home addresses in file paths, client names in commit messages, GPS tags in photos, and internal codenames inside diagrams can disclose patterns attackers exploit. Learn to scan exports, strip metadata, and rewrite examples so learning remains intact while sensitive context becomes unrecognizable to scrapers, recruiters, and well-meaning amplifiers who might spread details much wider than you ever intended across platforms and aggregators.
