I've come back to this because I think it's important.
The existence of bot farms has been verified:
www.gov.uk/government/news/uk-exposes-sick-russian-troll-factory-plaguing-social-media-with-kremlin-propaganda
"UK-funded expert research has exposed how the Kremlin is using a troll factory to spread lies on social media and in comment sections of popular websites....
"The research exposes how the Kremlin’s large-scale disinformation campaign is designed to manipulate international public opinion of Russia’s illegitimate war in Ukraine, trying to grow support for their abhorrent war, and recruiting new Putin sympathisers."....
[and]
focusing activity on posting comments, rather than authoring original content – a tactic likely to decrease the risks of being detected by social media platforms for engaging in coordinated inauthentic behaviour and/or harmful content

That's bots and shills. (bots being automated programs who post comments, shills being real paid people)
Again, keep in mind
"According to the Intelligence and Security Committee Russia report, released on 21 July 2020, there is substantial evidence that Russian interference in the British economy and politics is commonplace"
(en.wikipedia.org/wiki/Russian_interference_in_British_politics)
I think that it's odd to believe that the UK and even a forum like mumsnet would be targetted, but the statement by the govt indicates this -is- going on (it's a big UK forum) and as I said, and detailed, in a previous post, after a time you learn the signs to watch out for.
As it happened, I'd already encountered a shill some years ago. At first I thought they were posting in good faith, but then realised there was something with his slipperiness and the absolute refusal to listen to people who had direct personal experience of living under Soviet rule, plus the consistently distorted or uneven way he presented facts and events.
I'm afraid that since the beginning of this war there have been a number of shills and on this thread there are indeed some posters who have exactly those characteristics.
I've followed the war fairly closely and there seems to be directions from the Kremlin as to the line to push. At times it's quite funny - when Zelenskyy went to the US, a whole pile of accounts started pushing the line that "it's terrible that he didn't wear a suit"... all in exactly the same phrasing, posted with the same time stamp. There's coincidence, and then there's not.
