That is not the definition of curation:

> In smaller organizations, a curator may have sole responsibility for acquisitions and even for collections care. A curator makes decisions regarding what objects to select, oversees their potential and documentation, conducts research based on the collection and its history, provides proper packaging of object for transportation, and shares research with the public and community through exhibitions and publications. In very small, volunteer-based museums, such as those of local historical societies, a curator may be the only paid staff-member.

> In larger institutions, the curator's primary function is that of a subject specialist, with the expectation that he or she will conduct original research on objects and guide the organization in its collecting. Such institutions can have multiple curators, each assigned to a specific collecting area (e.g., curator of ancient art, curator of prints and drawings, etc.) and often operating under the direction of a head curator. In such organizations, the physical care of the collection may be overseen by museum collections-managers or by museum conservators, with documentation and administrative matters (such as personnel, insurance, and loans) handled by a museum registrar.

If the second type of curator starts "filtering" the museum's collection, they're likely to be fired and possibly sued or even criminally prosecuted. Of course, acquisitions and exhibit curation do involve filtering.

Using the word "curation" to mean "selection" — possibly even automatic, unconscious selection, rather than selection by a subject specialist or even a conscious being of any kind — trivializes actual curation.
