For example, every now and then I check what some elected Canadian politicians have tweeted recently.
Even though these are Twitter accounts that would probably be considered "real", and they often have a check mark, pretty much everything they tweet is, in effect, following a script.
Often, these tweets are just a useless acknowledgement of some obscure holiday celebrated by some unrelated ethnic or religious group that they want the votes of, or they're tweets delivering pointless congratulations for an irrelevant "accomplishment", or they're tweets regurgitating some very specific party talking point that a bunch of other representatives from the same party are simultaneously regurgitating.
These accounts are seen as "real" accounts corresponding to "real" people, yet what they produce is consistently some of the most artificial content I've ever seen.
