There has been some discussion about a developer's ability to flag inappropriate reviews. For example:

If developers believe a review violates Garmin’s Terms of Use (see https://www.garmin.com/en-US/legal/terms-of-use/), they may flag reviews of their own apps they believe are inappropriate and provide a reason explaining why on the following form:
If the flagged review is in violation, the review will be removed. We also encourage developers to reply to reviews to help address customer concerns and direct them to the Contact Developer link if further assistance is needed.
This has been documented in the New Developer FAQ for reference.
