I think you raise another very serious question. We have seen this in the States, that some of the techniques that were pioneered by foreign activists are now being adopted by domestic activists because they've seen that they work. It has the same kind of concerning effect as promoting discord, and hate speech sometimes, and gathering from the crevices of the community people who have views that in isolation might not have much power but that, when they are able to find each other online and promote these ideas, become much more concerning.
We don't have good tools to go after that, because it's easy to say, if it's foreigners, that they're trying to intervene in our election, and we know that's not a good thing. When it's our own people, though, it's a bigger challenge.
