BTW, re Twitter and other influence campaigns.
On the Russian invasion threads we've been talking about the sheer spread of Russian information campaigns; the way they poke their sticky fingers into every useful-looking issue to promote division.
The Russians are ubiquitous, but they're not the only ones to do this. The technique of appearing to back one or both sides of any contentious issue, in order to heat the issue to extremes and division, is common to many interest groups.
The upshot is, any of us who have ever campaigned sincerely for any issue we hold dear, will probably at some point have had some lovely troll chiming in pretending to support us. Even attempting to lead the way.
Our natural reaction when this is discovered may be to feel defensive, and to deny that our "friend" in the cause is not in good faith. But the effect of this is to cover for the troll-master, who definitely doesn't have our interests at heart.
We need to get used to acknowledging that whatever we're doing, it's likely some "supporters" will be in bad faith. And then get on with the campaigning anyway.
