Promoted FB posts are a very bad measure of what is happening. They are designed to provoke people and get reactions - it is all about engagement.
I do not know what the motive is (some way of making money no doubt) but it is clear to me that these are mostly just trying to get comments and reactions.
I strongly suspect a lot of what I see on FB is not even human written - lots of jokes that do not quite make sense, minor variations on things I have seen before that also do not quire make sense.
There's also reporting like "Officials today launched an investigation after one of Sadiq Khan's electric buses exploded during today's rush hour". [1]
"A huge blast ripped off the back of an Optare Metrodecker 1050 bus"... yet the picture shows the back of the bus is intact. [2]
Daily Mail nonsense like this was enough to influence the Uxbridge byelection (over LTNs), but I'll admit I'm too far away from Britain to know the situation.
