You report clear violations only, if they state gold plated then you report the listing. You only have to overwhelm them with genuine and obvious violations for them to take action to clean up the fine jewellery section. It hjas to be about the volume of the reports and for this to work is has to be a very obvious violation.

it depends on how eBay grade the violations. eg I have reported sellers who have stuff listed in fine jewellery category, "solid 18ct gold" in the heading, item specifics say "Material: Gold", in the descriptions it clearly says at least once eg "Women's Solid Gold 18ct Bracelet" and yet ...

further down in small print it says "all our items are Gold Layered", so they seem to get away with it, even though they have breached SEVERAL eBay policies like, 'misleading heading', 'search engine manipulation', 'wrong category' etc.

And, Yes it has to be about the volume of reports. It's pointless one person reporting someone no matter how blatent the violations seem to be.
