I sell invitations on Ebay and luckily I have been so successful that it has become my main source of income.

Yesterday I came across two sellers who have both blatantly ripped off my designs. Place my original next to their rip off and there is no difference - except the quality of the work.

I have sent a cease and desist letter to both.  One apologised and removed the offending listing straight away.

The other has not replied and is not removing her listings, in fact she listed another.

Today I did a quick search and have found the seller who refuses to take down the listing has 2 accounts from which she is selling exactly the same items.

Is this even allowed? And if not, how do we report it?
