Yes, they will. And they will post, too.
I saw the end of a discussion about the situation in Russia on MN the other day, and from what was left of the discussion I think a bot had been identified and blocked for posting propaganda. Prigozhin is infamous for owning 'troll farms' which publish disinformation all over the Internet, so it may have been something to do with that.
On a smaller scale, 'nudge units' and media scanners definitely operate online - whether GN is big enough to attract them I don't know, but it wouldn't surprise me, as we represent a defined demographic which is more likely to vote than others.
I agree Doodledog, but I do think one of the strengths of Gransnet is the ability of many of the regular posters to sniff out and report trolls. It always surprises me how extreme some peoples views are, but they are easily recognisable as ‘belonging’ in our demographic or not. Trolls aren’t generally that good at understanding how we tick.
