If this is from a context:
MEGA does not have a public search engine. You cannot type "daredevil qxr" into MEGA and get results. Instead, you need a direct link or a third-party indexer (like MEGA Search, MegaIndex, or Reddit-sourced links).
The answer lies in the psychology of the user interface. We have become accustomed to relying on autofill and suggestion features. Sometimes, a user might see a strange suggestion in a dropdown menu and, out of curiosity or by accident, click it.
