For non-toxic, non-sensitive general feedback like this I encourage users to post a Topic in the Contribute > Site feedback Category. The advantage of this public approach for feedback is you can include the whole community in discussions on approaches and solutions to things and people can see prior discussions so you (and others) don’t have to repeat yourself. Why hide this stuff? You might even get long time members helping others out so you don’t even have to intervene! 
This use case is already implemented and catered for in the Post flagging system. It’s even better because it references the exact Post.
