Um...you may have kicked a sleeping dog when you asked Ebay. Either that, or a competitor reported you.
I'm too lazy to pour through the policy right now, but there are literally thousands of tapes like this for sale. I really do not believe you were in any violation.
Actually a better place to ask (if you think you have to) is in Ebay's answer center under community...those folks are good Just member to member, like this is.
