Being Scottish and spending time in r/Scotland made this pretty obvious. Scots use language patterns, slang, and colloquialisms that come from Gaelic, Doric or Scots that needs knowledge and experience to interpret. Bots/paid brigaders trip up because they dont understand meaning or context. They are instantly recognisable.

There is 100% a well-funded project to influence political thinking. Mention anything about right-wing politicians, bigotry, lgbtq+ rights, the environment etc. and it triggers some action. They all pile on, thread makes it to 'all', thread gets locked. Rinse and repeat.
