Just to give the benefit of the doubt, could they have been deleting wrong entries?

If they left one or entered a new one I could see that happening, but if they did not enter a new record or left at least one accurate one, then give them a warning and if it continues, ban them?

Make it a point that when deleting records without entering new ones to replace or leaving one that is accurate is manipulation of Docbot and worthy of banning use.

Does it also log who entered in a record, just like when you delete a record?
