Clothing toggles bumping the fuck out of peoples poly/material/mesh count ever since the inventory system, penshader requiring multiple lights when two lights gets you directly into very poor, and boothbrains just uploading the unoptimised garbage the japanese shit out without touching blender.
I would imagine a fair few of them are perfectly fine on the optimisation front but have 70,001 polygons which makes them immediately very poor. The ranking system really should be points based rather than a single thing being over their arbitrary limits locking you into that rank.
