I can't believe how amateurish the persons behind blockchain.info are. I mean they have this great domain name and a really old and established project that many are using. But then they go ahead and do so many errors that it is not funny anymore.
correct me if I'm wrong but I think the fact that they are the most used bitcoin website only makes it even more difficult to keep everything in order. it's not like things will get easier as their users increase thousands daily.
True but they have made several mistakes over the years that simply point to bad software engineering. In this case they simply failed to validate transactions coming through their pushing mechanism. In other cases such add their android app, they used a bad random number generator.
I have to agree. Over the years an enourmous amount of problems came to light. And seeing the type of errors does make it easy to think that there are no professionals coding.
Anyway... they were not hacked till now. That is something that many other online wallets can't say. I remember wallets claiming to be ultrasecure, only to go down in short time.
