its been deleted as you are advertiaing what you make and sell,you are moaning because someone else is amking money from what you sold them,thats business mate get over it or pay the advertising fees like the trader who you sold your items too had done
another thing if you aint got a patent on your product unlucky,you should have also thought of doing that but at the end of the day the smallest of things can be changed to get around this
get over it mate as there is nothing stopping you trading on this site only your pride,lets face it you have had enough sales off this site in the past so maybe its time to pay
