Products/Items are missing from Site

Summary:

Periodically our over night processes fail to update records because the item no longer exits in OCC ADMIN. When we send updates we do not send any default prices. When we send a new item we send a 0 price, then the integration that sends pricing updates the record.

When the item is missing, in the default worksheet there is a delete flag set. I figured out why this was happening by looking at the import logs.

Is there a way to audit who or what could be removing items for the site? I am only seeing this in Production Site at the moment.
