Are you thinking of the US bombing Iran perhaps? Assuming they are running such a disinformation campaign (which is the theory you are talking about) why would they shoot themselves in the foot and cut their own spooks' connection off? And you're off by almost two order of magnitudes, the study in question found that 4% of pro-indy activity was linked to Iranian controlled attacks (and I am highly doubtful of Twitter's influence in that debate in 2025...)

I don't understand why we can't have both - are you saying that native-born Brits are inherently more trustworthy than people from other nationalities? Or do you mean that we should also curb internal migration as well?
