I have no problem with people reselling their gacha items, but my problem is that about 40% of the MP listings in many categories are all just gachas. For example, in the BDSM section, there are currently 19557 items listed. But, if you remove the no mod items (typical of gacha prizes), it drops down to 11310 items, which would make it roughly 43%. But, not all items that are no mod are gatchas, so just turning on no mod means I would miss out on legit items. Maybe require that all gatcha resellers stick to the used goods section of the marketplace? Or at least tagging their items as being used.
