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

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.


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!

    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? – amaclin Aug 31 '15 at 11:46

    Why do you use both the bitcoind daemon and blockchain.info API? – morsecoder Aug 31 '15 at 19:47
