FYI
I’m sure this woman is flattered that you took time out of your day to give her some feedback on her pictures. It is nice to see that there are still people in the world who genuinely like to help others. Constructive criticism is always appreciated. Especially when it comes from a random stranger.
It is always good to get some feedback so you know how you are doing. Your work here is done. It’s nice to see that there is some kind of quality assurance with these dating apps. Otherwise, who knows what kind of things people might post.
