Totally with you on this. For me, it's the sellers getting away with murder while I keep getting reprimanded for things I haven't done wrong.
Eg, when I report sellers for listing items as 'New' but describe in the details that the items are in fact used, and pictures also clearly show wear & tear, I get a CS reply of 'Sorry, this listing has not been taken down as we find it hasn't violated our policies' But then I've had a number of listings taken down for 'using copyrighted images' when I most definitely haven't. I've tried appealing and even said "do a reverse image search, you will NOT find my image anywhere else. This is entirely MY intellectual property, they are obviously MY photos" and I just get a repeat response of the first email telling me I'm going against their policy of using copyrighted images that don't belong to me. It's so frustrating! Now, they appear to have disabled the ability for me to appeal. I now can't say anything to defend myself.
Also, see hair styling tools - apparently ALL have to be NWT, absolutely no NWOT or used. Stupid rule in my book, as plenty of hairdryers, wands, straighteners, heated brushes etc could be re-used (or even repaired if listed for faulty or spare parts). However, everyone lists used hair styling appliances under NWT. But I'm not allowed to. Literally thousands of people doing it, but I can't.
I actually bought a used hair styling appliance from a seller on Vinted (listed as NWT. but described in details as used). It didn't give my fine fluffy unruly hair the effect I was after, so decided to sell on again, but it was taken down for being used.
Also an extraordinary amount of blatant scammers. Had one scam my son by listing a used and fake high-end brand as genuine and new. When we received it, I collected proof of it being fake and used, and the seller had to refund me. But the seller just deleted their account, made a new one and attempted to harass me demanding I send the money back that I got refunded.
The whole sizing change is utterly ridiculous. I genuinely dont understand why they use 4-6, 8-10, 12-14 instead of just individual sizes, with XS S M etc as well, with the ability to filter out multiple sizes if you're inbetween. The 'round-about' sizing is tedious when you keep looking at stuff that won't fit.
Hate this platform now and have stopped uploading anything new.
Might have to go back to eBay. I just find the details required for each item on ebay is relentlessly longwinded when you just want to make a few bob so they don't end up in landfill (or filling greedy chief execs and senior managers pockets in charities, while the supposed benefactors of charities get the tiniest percentage and shop workers get absolutely nothing).
