Wikipedia lists two bigger ones, but says the data is unreliable. Their estimated masses are greater than the theoretical maximum a black hole should have been able to reach in a universe this young.

Still not the biggest black hole we know of. That would be Ton 618, weighing in at 66 billion suns. 30 billion is still ridiculously huge though. There are galaxies with less mass than that.

I know a lot about the atrocities of the USSR, I don't really know what happened under the Czar. I was under the impression that the Czar was just an out-of-touch distant autocrat, not really interested in the affairs of the Russian people. Whereas the USSR took a keen interest in what the ordinary people were up to, and it wasn't to the peoples' benefit.
