Everyone is asking me that, and I have no way of knowing. I have no reason to believe it's because there's more wrongdoing. There is no data that would suggest that. I can't disprove that either, but there's no data that would suggest that.
In my career, I've seen the start-up of many new organizations, particularly those that render a service to the public. It takes a while for people who might access that service to even realize it's there and then, once they do, to have enough trust in it to bring it forward.
My best guess, because I have no way of verifying it, is that I do believe the office was established in 2007, and I think, at a certain point in time, there was a critical mass period when people knew enough about it to start using it, and that gave rise to more and more.
That is my belief, but I have no evidence or proof to say that. If you're asking what I think, that's what I think.
