Those are some good examples, I kind of feel bad for the first person you spoke about. It's understandable not being too active especially if you're creating pieces of art that can take days or weeks, on top of what else is going on in their daily life. But, a bit of manual curating can go a long way and really give someone a boost, sometimes comments are worth more mentally than a like, just to let the person know they're doing something right.
I think I read the post a few days ago of the second person you spoke about, was she the sister of the woman who passed away? It was very sad and was written very poetically.
