True, now that you mention it I’ve seen the same sort of thing from people who are definitely not bots. Although, you can’t discount the possibility that they do some government or law enforcement work as a consultant. The full throated defense of police state tactics is unreal. (For what it’s worth, there are plenty of Americans who show up in Palantir/Flock threads doing the same thing, and I have the same suspicions there.)
For a current example look at the other guy replying to my comments, earnestly trying to equate 'free speech zones' in the US which have not been a thing in years, maybe more than a decade, with people in the UK being arrested for holding up blank signs.
I can't imagine it's paid work because what would be the point? It's not like he is influencing anyone's opinions.
