hi
well to be honest i found a simple way to get private keys (from a website) , but the problem is i cant send the money to an other address when i import the keys to blockchain.info i get something like : "GETTING UNSPENT OUTPUTS" and nothing happens

i can put some private keys here if a respected member ask me to as a proof if required.
anyways im still testing all the private keys on blockchain , (im tired) i hope i get some good money soon.
and if there is any help i will be very happy.
Thank u.
I'm not sure about this, especially with the "hacking"
But anyways,
for any address in general:
1- Check the balance using the address itself instead of the private key. It might have a 0 balance
2- "Getting unspent outputs" basically means that blockchain.info is checking your balance. Not sure about after that
For any address in general, try other alternatives if blockchain doesn't work. Electrum is lightweight, you can try that.
