If you're selling Adult products, it's possible to mark them as Private Listings inside eBay. This will have the benefit that the list of previous buyers of a product are not displayed, and your customers may appreciate the anonymity!
To designate yourself as an Adult product retailer, navigate to Settings > Administration and tick the 'Retailer sells in Adult categories' tickbox. Your listings will be made private on the next feed refresh.
