I have 3 service that use blockchain.info's API. Very strange transactions happened on march 4. I was digging logs for couple of hours than I realized that blockchain.info made all my transaction anonymous. This is a huge bug because anonymous addresses expiry after 8 hours but most of my bitcoin payments arrives after couple of days!
I could easily loose 30 bitcoins but thanx god I just "lost" 1.96 bitcoins. (I can prove it and I sent the logs already to support.)
They admit the bug & promise me refund but I did't get any bitcoins nor any answer for 13 days.
I hope this topic help me get the refund (Zendesk #2371).
Blockchain didn't lost this bitcoins since they have the private key for all addresses and already moved my "lost" bitcoins.
Trust no one and trust no ones API.
PS: mods pls move this topic to the right place.
UPDATE: I got the refund.
