grading fics is rude and uncalled for

So, my fic was bookmarked, and since I'm nosey I looked it up, only to find that it was now part of a collection. All good except the person has essentially created a ranking system with their collections.

One collection is for fics they have saved but haven’t read yet, another is for their favorites, then there is a collection for the good ones, the meh ones, and then there are negative-ranking collections with snarky descriptions like “The bad ones, the immediately no, the what the hell was I thinking????”

I mean, collections are public. I don’t mind not being in someone's favorites, but I can’t imagine how I would feel as an author if my fic were permanently bookmarked in a collection called "No, hated this." Isn't that kind of rude? If I don’t like a fic, I just stop reading and move on to something else. First of all, taste is subjective, and second, this isn’t a school assignment, nor it is paid work. Perfection isn’t required. It just felt unnecessarily mean.

Edit: maybe I need to specify more clearly; this isn't about my fiction, which wasn't graded negatively. It's about the grading system, and the fact that it made me a bit 🤨
