Produce arguments for and against Ebay.
Dont let the fact that they earn a billion gazillion each year, or you have had a bad experience with them, make you think that they are liable for this, unless ofcourse, you can make a valid argument.
Basically Ebay have been and are still being sued over the fact that they are selling counterfeit goods.
Ebay argue that they are not responsible for this, as they are only providing a trading platform for the public to use as a buying/selling ground.
If knock-off nigel was selling knock-off dvd's at your locals, would the landlord be responsible and fined?
Personally i dont think Ebay are responsible for policing counterfeit goods. If you sign up to their site and sell goods, you, as the user, are bound by their terms and conditions. If you dont like them you dont sign up. So ideally, you as the user are liable for what you sell and if you as the user break the T&C's then you as the user are to be held responsible, no?
