You won't be well versed in the vernacular of any political event unless you follow the news. But that's just as true for native speakers. You seem to imply that people who learn tens of thousands of words to communicate in a foreign language would be unlikely to learn the additional vocabulary of the current events. Especially the big events. Could anyone with a British friend in Twitter never hear of the NHS bus, for example? Unlikely.

Unfortunately, as with any form of communication, the only way to know where something really came from is to find the source, whether an individual or a collaboration. Facts are still being discovered about decisions, choices and actions relating to Benghazi, years ago. Obfuscation of the source is intended to delay. It works. Masking the source behind fingers pointing to cultures is a "cheat", and cheaters do not like to be discovered. Personally, we have been presented with evidence of tools and techniques of Alinsky in the 2016 U. S. election.
