But I would not say that this failure was a successful outcome, at least not nearly as successful as it could have been. They had to shut it down within hours and all we really learned is that people on the Internet like to troll with incredibly offensive stuff. Most of us knew that, I'm pretty sure. If they had actually prepared for abuse we might have learned more interesting things.
What really gets me though, is just the obnoxious spin on the press release implying that they had prepared so well for abuse but a sophisticated coordinated super-hacker attack found the tiny vulnerability.
