My initial thought was for them to start their own posts in a news community and then provide their own thread of comments within that post. This way they wouldn’t have to do anything different from mastodon but both platforms would get to see their threads.

But then, it seems news communities like World News on Lemmy.world kind of have rules against posts to social media content. Maybe an exception could be made for this person because they are constantly citing primary sources.

Otherwise I’m not sure what else would be the best spot for such a thing.

Any suggestions?
