I think the governments should get together and setup a task force. Spend a few million dollars and order something from everyone selling online. Then they could check for illegal or knock off items. Also if the seller shipped as a "gift" or is legally selling and shipping their items. Impose big fines and take away their ability to sell online. How many sellers buy stuff from China to resell? Some is legal and some is not. It would clean up the market place big tme I think. Same as on ebid. If you ship items as a gift you are no better than the criminals that put the illegal goods on the market in the first place. My thoughts alone of course which usually come under attack. That does not bother me.
edit: The legal items they could resell through a legit outlet to recoup some of the money spent.
