Look at it this way, would you rather have the blockchain stop for a few hours or have someone give himself 37,898,000 SP out of the blue? Which do you think would have a more negative impact on the network and ecosystem?

Hey @pfunk. Not at all ungrateful that the transaction didn't go through. If we're talking about what I would rather, though, I would rather neither happen. Someone shouldn't be able to give themselves nearly 38 million SP and the blockchain shouldn't shut down for all of us. The filter for such transactions shouldn't fail.
I think we can agree on that. I think we also agree that stopping the blockchain is better than the transaction going through. The questions remain, though. Is there potential for more of these 'unusual transactions' and if so, will anything be done about them before someone else accidentally or maliciously brings the blockchain to a halt again?
In software development it's impossibly optimistic to think a complex piece of software will be bug-free. Developers of course try to think of all of the ways something might be exploited but all the bases are rarely covered. There are numerous checks and transaction rejections in Steem, for some things less obvious than others. Often it's the exploitation of a bug that identifies it and drives it to be fixed.
Of course ideally the blockchain wouldn't stop and the transaction would have been rejected. But much like @timcliff said, considering the circumstances, the outcome wasn't too bad.
I have worked for a company where there was a formal requirements process with full traceability in place, we had solid DTAP environments, programming was done in Ada, code and module reviewing and testing was done in an almost religious way, and we had a very competent and creative dedicated FMECA team, and also aggressive alpha and beta testing, and guess what ...
Shit happens. Having shit happen less often is very expensive, and even then there are no guarantees. Still, my trust in the quality of the blockchain codebase did take a small hit, can't help it. Well caught and solved, though.
