I was just over on Reddit reading about how Hillary Clinton is paying people to frame the political narrative on social media/large websites. I'm certain that Mumsnet has seen this sort of activity too, fake posters with an agenda. I've seen it in the education section in a straightforward form, and around Brexit there was lots of it going on in the politics sections (I think Dominic Cummings was involved in both cases).
Anyway, I was reading this article about 'How to spot a shill' www.inquisitr.com/3398783/how-to-spot-a-shill-in-eight-easy-steps/ which is advising supporters of Jill Stein (Green Party presidential candidate) of the methods which will be used to try to dent their support.
In reading the article, I was reminded of several recent posts/threads in this section.
The gamergate thread which seemed to be aimed at undermining Anita Sarkeesian (I think she's done some good work but has acted shadily) cloaked as a feminist discussion about sexism in gaming.
Decoy insults - Kids are dying while you talk about this irrelevant stuff. Women in actually oppressive countries are laughing at you.
Divide and conquer - now I've no idea as to the truth of any recent allegations, but suggesting that people on one side of an argument are sending abusive PMs to those on the other would seem to fit the bill.
Anyway, I'm sure those that post more regularly in this section would be used to/aware of these tactics (I'm on half term, I usually stick to education), but I thought it was interesting and something that all users of the internet should bear in mind these days as use of these tactics will only increase and become more subtle.
