It's not hypocrisy, it's just that the site is too massive for eBay to check each and every listing on their site. At any one time, there are 7 billion items for sale, so invariably some will slip the net and become listed.
Yours was spotted and reported and so removed, once those others are spotted if they too breach a selling regulation they too will be removed. eBay also rely on members to report items, there's a report button down the right hand side of every listing.
One thing is certain please do not try and relist the item, this might bring about severe sanctions on your selling account.
You will need to find another site without this ruling to sell your item, or perhaps even look to an auction house, this items sounds as if it might do well there.
