I'm just assuming this because it doesn't say anywhere,
but given the context it seems likely to me that almost
none of the 900000 domains were actually registered.

It sounds more likely that they figured out how the domain generation
algorithm works and instructed the registries to block out all the
possible domains it could generate (preventing them from being registered in the future).. along with also going after the registrars to disable a much smaller
number of domains that were actually currently registered.

Could be the 0.01% were the ones that were actually registered.

1. Which is why abusers are registrars' best customers and why
(some) registrars work so very hard to support and shield them.

2. As an aside, I've been doing a little research project for a
few years, focused on domains.  I've become convinced that *at least*
99% of domains belong to abusers: spammers, phishers, typosquatters,
malware distributors, domaineers, combinations of these, etc.

In the last year, I've begun thinking that 99% is a serious underestimate.
(And it most certainly is in some of the new gTLDs.)
