Do you know when to delete instead of disqualify a lead?

<introEmbed body={<> When going through leads to see if they should be converted to an Account/Contact/Opportunity or disqualified, any that do not contain contact details should be deleted instead of disqualified. The reason for this is that there is no benefit having only a name in the system, and it could produce false duplicates later if we were to import or create someone with the same name. </>} />
