these look like huge chunks to add in htaccess

Huge chunks are good. One sweeping /10 and a whole section of the country is gone. The maddening ones are when a Ukrainian robot is perched on a /24 between two perfectly innocuous pieces of France.

Yup. Out of an almost-900-line file, about 2/3 is China. Add in my site-specific htaccess and the total drops to about half. Oh well.
