You can make a stealth listing where the person would need the URL to access it, but as far as I know it's not possible to create a listing that will appear in a category but not in your listings on your vendor page. Perhaps you could create a stealth listing and start a thread where you post clues that people could use to figure out the URL. For instance, if the URL were http://silkroadvb5piz3r.onion/silkroad/item/eghd4cb967 you could release a clue for the 10 character unique item URL; for example: "This popular children's poem character is a delicate chap and really cracks me up - what is he (3 letters)? (First two letters of this word are the first two letters of the URL)" Just an idea! Libertas
