Supported source definitions and Safe Mode coverage.

Coverage is broad but uneven, and that is by design. The largest categories are the ones where public profile patterns are predictable and where handle reuse is most common. Online communities make up the biggest visible share of the catalog, followed by gaming and technology platforms, then marketplaces, hobby sites, music, image hosts, and developer tools. Smaller visible categories such as finance and travel have only a few definitions each, so a quiet result there says less than a quiet result in a well-covered category.

Read coverage as a hint about confidence, not a promise. A handle that appears across several well-covered categories paints a richer picture than one that surfaces on a single niche site. Either way, a source definition only means the tool knows a public pattern to check. It does not mean the platform provides data to WhatsMyName, endorses the site, or vouches for accuracy. Third-party names appear solely to identify public sources and remain the property of their owners. Safe Mode hides sensitive-category sources from the default public catalog view.

Public platforms also change without notice. When a result matters, open the public URL and confirm it with your own eyes. If a platform looks unavailable or returns the wrong result, let us know the source name and what you observed so we can review it.
