Objects on Scout, which are drawn from the NEO Confirmation Page, will eventually leave as they are desiginated as an asteroid (NEO or otherwise), removed as not existing or not a natural object, or (in very rare cases) by impacting the Earth.
ScoutDetail objects will continue to accumulate over time, which does allow the history to be preserved and analysis performed, but may create issues with having to deal with an ever-growing amount of stale objects. There is a last_run field which is when the object was last updated by Scout, but it may be more efficient to use a simple boolean 'active=True?` flag.
