There was certainly a lot of learning for MI5, MI6 and the Foreign Office about the destabilising online tactics of groups of rumour-mongers being manipulated by Russian interests. It's interesting that the umbrella phenomenon is being given a single name - Doppelganger - but it's clear that it applies to a whole disinformation network.
I imagine, as I've said a few times, that the tactics of many of the sacchari are under scrutiny, all the way up to the principles, focusing on not just content but sources of traffic and exchanges of money, good and services.
Do posters recall how many sacchari disappeared from this board and MN in tandem with Catherine's video statement about having cancer treatment?
