I'd like to believe you. But every time I ask any question of your support personnel, I get the same scripted response. "There is an API you can use" "why don't you post this in the forums" "we read the forums"

For this particular issue, what roadmap do you need? this is a simple request that is just a simple filter for a Zendesk programmer. There is no mind-altering earth-shattering changes to the product required to implement this. I'm assuming that standard answer "you can use the api" means that zendesk can also use its own api to add a simple filter for suspended users.

5 years of ignoring this simple request is just bad customer service. Every answer your support reps gives me that is no help at all beyond telling me it can't be done unless you use the api is bad customer service. Period.
