The seller of the first fake,
leviuva should definitely have the listing reported.
You can count me as another who doesn't recommend contacting sellers to let them know their items are fake. Some know exactly what they're peddling and don't appreciate getting "caught." And if they report your unwanted message to ebay, even though you did it with the right intentions, YOU can get suspended for misuse of the messaging system.
A better way to send the seller a strong message is to report the listing and hopefully, when ebay removes it, the message will get through to the seller.
In this case, I don't recommend
leviuva because even when she was told that the bag is fake, she left the listing up and running, possibly allowing another buyer to get scr3w3d.
Please report!
