Re: custom .onion address?
It's a little scary actually. But yeah they brute forced the whole thing. I doubt they were specifically aiming for the corewwwi part though. More likely what they did was generate tons of these, and filter for facebook<words>.onion and then have a human look over the results to pick one that kinda made sense.
Still, it's an impressive achievement, and it probably means the 16 character addresses won't be good enough all that much longer.
