They’d probably have to outsource it. It’d be very expensive hiring thousands of people to do it in Europe full time and they have to be native Russian/hungarian speakers to not get immediately caught. They’d have to be connected to the pulse of the local culture.
Popular posts on Twitter, Facebook etc have tens of thousands of likes and comments. It’d be a major operation to do it and might not push the needle.
The scale of the Russian one caught in the US in 2016 was pretty small. They were spent about $400k on FB/twitter while the campaigns spent about $2 billion and PACs spent $4 billion (about 15,000x more).
