Now that the new CSAT Experience is out, I am posting to this thread again as the page discussing the new CSAT experience is locked for comments.

https://support.zendesk.com/hc/en-us/articles/8056511676570-Announcing-the-customizable-CSAT-experience

Please let us know if and how we can do more with CSAT in terms of deletion or hiding of erroneous CSAT that affects our agents.

This has been a request to Zendesk Product Team for at least three years. Please see Briana Hansen's initial comment above
