How can this be abuse?

Hi, there is no need to tag everyone please.

No, you weren’t. I can see that the submission in question was rejected for not meeting any criteria. Per our assessment, it is a street sign which is not eligible. The text string you see is tied to the reason selected internally. I admit it requires an improvement. Coming to the warning, I can confirm that you have not accrued any points on the abuse ladder. It was meant to be an educational message.

I have not looked at your nomination or its context but just to clarify the misbehaviour thing: it looks like a Wayfarer team rejection (broadly, for things that include non-abusive things such as ineligible objects) currently displays the kind of text you see. I agree it is unhelpful feedback-wise. But if you did not get any warnings or ban emails otherwise, there is no need to worry about this.
