I think it's worth not taking a 'Mastodon exceptionalism' approach to disinformation.
The lies that have acted as a spark for this week's riots in the UK might have spread primarily on mainstream social media, but there's no systemic reason that the same couldn't happen here.
Mastodon does not have immunity, it simply has a lower R0, primarily for the fact that early adopters tend to be those that turn a more critical eye toward information technology by their nature.
I've seen a fair bit of overly-eager brigading going on here over false information (generally of a much less harmful nature). No doubt it's a massive improvement on Birdsite and Zucksite, but it's a difference in magnitude rather than a difference in kind: and as Mastodon grows, so shall the magnitude of the problem.
