For what is worth I think she earned the “Likes”
Although you might not like the editing and the addition of those hearts, the photo is not technically bad. I see correct skin tones and good exposure although it is a flat image.
Maybe this was a request as I do not see other similar photos in the 1000 or so photos in her profile. I do not know this person and I live in a different continent, therefore I have no interest in standing up for her. I do think that you are a bit unfair to her, especially compared to your FB page. She is obviously at a higher level.
