Two years on and Zendesk still don't have a solution to this. We have many thousands of legitimate customers who use qq.com emails so blocking the whole top-level domain is not a viable solution (or appropriate suggestion).

Like others here, I will not endorse a solution to require our many millions of customers to create accounts to get support. This is a high friction flow that is not appropriate to introduce to our consumers when there are fundamental failures from Zendesk to deploy effective bot protection.

Deactivating HC is also not viable for our business.
