One of these days, we writers at Techdirt will put our collective and enormous heads together, and come up with an actual proposed mathematical formula that should be applied whenever a company first announces a security or account breach, so that the public can calculate what that breach count will eventually end up being. The reason the world needs such a formula is because you can pretty much set your watch when a company announces such a breach that in the following weeks or months it will grow significantly. This happened with Equifax, with TJX, and even with our own vaunted federal government. But if we ever really did want to try to put some kind of formula together for measuring the underplaying of a breach on initial response, the historical breach that would probably brake such an algorithm would have to be Yahoo's email breach, which, in 2013, was the breach of a few hundred thousand email accounts, but in 2017 magically became all of the accounts. As in, literally all of them.

This severity progression is so routine that it should have a name for easy reference. I propose Geigner's Effect. I heard somewhere that if you write for this site long enough you get an effect named after you.
