OMG, this is all so true.
That user number thing is so annoying, and done deliberately to confuse. A few reporters have been rumbled on twitter as having secret secondary accounts around sm.
I do notice the only people who get called out are the ones defending H&M. No one ever questions the anti-H&M posters (even when most parachute in out of nowhere with outright lies).
Then other posters seem to really observe posters and trying to find out as much information about them personally as possible. Someone once complained about me not sharing much Information as to who I am. I kept thinking, what has that got to do with the subject. I revealed something about an ancestor, next thing I know I am labeled a nazi on another thread - yet I'm busy defending a woc too? (that ancestor had nothing to do with nazis, btw)😁
The concentrated gaze does creep me out. Then there is the stalking around not just threads, but boards too.
Well, I get hounded for things I posted ages ago. I don't necessarily apologise for it, as I still believe what I posted, but the proof was not definitely slam dunk (something required as compulsory if you are not an H&M basher, as you will know. But you can post all sorts of made up nonsense about H&M 🙄). Then a new name confronts you about what you posted years ago.
Posters also seem to analyse your style of writing. Someone is currently confronting me on another thread as we speak. I'm not young, but work with teens, so may have a specific lingo (naturally for informal setting, I guess, which I consider sm to be). I joined ages ago, when MN was still in it's infancy. How time flies. Things are different now. Been on and off over the years, but the scalding vitriol over MM has been different, particularly vile and quite hard to take even as a bystander. Other royals do not have this level of hate, no matter what anyone says.
My DC are so advanced in tech, one (not even a teen yet), once said "oh mum, so many people are trying to track you, a lot from that Mumsnet". Fortunately, my computer blocks most.
