Yes, there are: more things than you’d expect. It makes sense that you can’t buy firearms, for example, but you also can’t buy fireworks – eBay are worried about the risks of sending them in the post. Laws in many countries mean that you can’t buy alcohol or tobacco. You can’t buy illegal or prescription drugs, stocks and shares, or lottery tickets. No underwear, either. You can’t buy any little pet puppies or kittens, as animals are banned. If items infringe on copyright, like pirate CDs or software, then they’re not allowed either.

eBay's policy is controversial, not least because it is somewhat random in its enforcement – and there have been accusations that they’re more responsive to the copyright concerns of big businesses than to auctions for items that might actually be dangerous. If they do decide to go after you or the seller, though, they will cancel the auction and may also suspend your accounts.
