This doesn't work in practice. Transactions using Bitcoin "addresses" are just one (out of many) transaction types. As far as I understand the protocol it's possible that you receive those coins via a transaction type that doesn't have an associated Bitcoin sender address.

"Every wallet that receives funds from a tainted wallet becomes tainted" doesn't (in any way I see) conflict with the notion that there are transactions without a sender.

  I meant the "until you send it back part". If "every wallet becomes tainted" and "you can't send it back" this would make it trivial for an attacker to taint a large number of wallets in the Bitcoin network.

    If there is no sender, how does the receiver become tainted?
