I have to agree with William.
According eBay forums, you may have limits placed on your account or on particular categories and items until you confirm certain information or establish a positive selling history. eBay also encourages getting positive feedback - a number of them! These limits help you become a more successful seller, in addition to ensuring a safer experience for all eBay members.
There are 3 types of limits - Account limits, Category limits and Item limits
