There’s a Fediverse drama sub, but it’s about recording rather than disproving drama, and doesn’t allow drama to be posted by anyone involved in the drama.
This is more about disproving false claims that come about in the process of Fediverse drama, and allows people to bring up their own cases, so long as they come with evidence that the claim is false, and not just counter-accusations or unsupported denials.
Both of the top rules of the Fediverse drama sub are kind of antithetical to the point of FediverseSlander.
