You already have several potential violations of Ebay rules, and one of the tPF forum rules as well. I suggest you read the rules of both sites.
1- If you think the bag may be fake you should have removed the listing. You CAN'T sell anything on Ebay unless you can confirm beyond doubt that it's authentic.
2- You're reusing your original seller's photos in your listing - that's also against Ebay rules unless you have the express permission of the owner of the photos to do so.
3-
You CANNOT post links to your own auctions or sales here on tPF. That's considered "advertising" and can get you banned from the site. Your original post or at least the link to it will probably be removed by the Mods.

Under Community Guidelines - PURSEFORUM Rules it states:
"Linking your own auctions is not permitted, in posts, signatures or otherwise. This includes eBay, Bonanzle, eCrater, iOffer and other auction-type sites."
If you think something's fake it helps to explain why. If it's because of something you found in some online "authenticity guide" it's probably completely wrong, since I don't see any problems with the bag.
Sorry to be so rough when it's your first post but whether it's about posting here or selling on Ebay the Rules are important. Violating them at Ebay can cause more problems for sellers than just having a listing pulled.
