Blockchain.info is messy. Wallets get corrupted very easily.
I have had to change 5 - 6 wallets so far for my customers using blockchain as the back end for their projects.
I have stopped using them.
Never had any issues with blockchain.info's wallet service and I guess you probably don't have any idea of what you're talking about, right? "Messy" wallets?
Try the Api to send a payment to the same account and the wallet gets corrupted.
Had this problem when customers tried to demo their build using the same wallet. An error asking for a number between 1 and 1000 comes up.
May not be entirely bad, but small problems like this are not good for applications.
Maybe you were ignorant of this problem, right?
