<p>I added bitcoin payment to my website with bitcoin daemon, but one user is having an error with the blockchain.info API:</p>

  <p>Warning! this bitcoin address contains transactions which may be double spends. You should be extremely careful when trusting any transactions to or from this address.</p>

<p>Should I confirm this user's withdrawal, or should I block them? And what is significance of this error? If I use bitcoind to count confirmations, it's not dangerous to accept funds from such an address, right?? Thanks!</p>

Do you have a service which accepts deposits and withdrawals? Can you give an url? Do you know the address 1PN9vEwey7iikTHoKvrrUGJY7PtymhyNNV? Is it the deposit address of your service?

Why do you use both the bitcoind daemon and blockchain.info API?
