It is actually fairly plausible that Stoppelmann has no idea at all that his sales representatives are  using such shady tactics.<p>That is not, however, good news for Stoppelmann. Not in any sense. It would indicate that, at the client-business level of interaction, there is no functional oversight at all. That Yelp's management's either willing to turn a blind eye, or are so negligent as to allow this to occur even in the face of growing criticisms.<p>Incompetence or malevolence; either way, they're in trouble.
