The really pathetic thing about this is that trademark law requires ebay to protect their rights, so all they need to do, really, ask you to pay them a license fee for infringing on their trademark. This could be just a dollar, and they would have legally protected their rights. Sending a cease and desist is just being assholes. If they did not. Provide full contact Info, including a mailing address, then this is likely a scam- any law firm is going to give you a way to contact them. If they dont, then what they demand is impossible and thus the notice is not valid. Around 8 years go i got a c&d from some company that believed they owned the tm on a generic word and claimed my two word domain infringed. Ignored it, still have the domain, no further action, other than some stupid threatening demands from them.
