Seems like you probably are not explicitly stating this policy beforehand? It's not very surprising that explaining why you don't do as an applicant might expect afterwards is not going well. From the Github examples you've linked earlier, right at the end:

> When you’re ready, let us know and we’ll schedule it for review. We review submissions once a week. You’ll hear back from us no matter what by the end of the /following/ week, possibly sooner if you submit early in the week.

+ 1 sentence expressing "we will tell you if you passed or failed, we have a policy of not providing actionable feedback"

> Remember, we are not timing you and there is no deadline. Work at your own pace. Reach out if you're stuck or have any questions. We want you to succeed and are here to help!

+ 1 sentence "but make sure to not spend significantly more time than X hours"
