The title should explain the basics, but it truly is horrible. It's not good across most of the platform, but this category stands out. Whoever did the categorizing here was grossly incompetent, as that genius seriously put down rope for bricklaying "material group": "stone" and "material": "stone" (they are nylon; it's stated in the item description). But the problem is way more extensive than that. Like, if you're looking buy a rope "material group": "fabric" is completely worthless, yet somehow there's 186 ropes in that category from flax and cotton over latex-cored and recycled blends to polyester and polypropylene. There's also various ropes with (and only with) group "metal" because the item contains a metal piece (eg. a bungee cord with a metal carabiner), but yeah, the rope itself that makes up >90% of the item definitely isn't metal and that's kinda an important thing. More generally there should really be a "material group" for blends of natural and synthetic fibers, and it's kinda baffling how that doesn't already exist, considering it's actually really needed in countless categories (almost bought a "cotton" yarn when I was filtering for "plant material" that was half synthetic fiber). Nobody specifically searching with the filter set to "material group": "plant material" wants a blend with synthetic materials, regardless if it's about rope, twine, fabric, netting, tape, etc., etc. And usually somebody filtering for synthetic materials doesn't want a blend either. There is a forum thread at another end of the platform that also talks about the previous paragraph, but that thread is years old and yet the problem still exists.
