I contacted a seller to today because I believed the item she was selling was fake. She has very good feedback, perfect in fact, but the item she was selling was definitely a fake. 100% confident. Normally I would just report it but because she had such good feedback and this is her first fake item (that I could see) I thought I'd email her (maybe she didn't know it's fake) to warn her that selling this fake item could potentially harm her reputation. She told me I was being rude and totally discounted my reasons for why I believed the item to be fake. She said her friend who's a big fan of the label said it looked authentic based on the pics she's showed them. Should I have contacted her? Or should I have gone straight to eBay? She said she had reported me to eBay. For what? Did I do something wrong by contacting her with my concerns? What can they do? Next time I will mind my own business.
