@Djan, I would do two things.
The first: add to the posts by Hildmann a Discourse tag, for example #ethno-hildmann. With this, it is easy, both in Tulip and in the future multi-tenancy Graphryder, to induce the SSNA of that particular group of posts.
The second: add the #ethno-hildmann posts to the ethno-poprebel corpus. We have a way to reduce the bias implied by an over-representation of Hildmann’s thinking in the corpus, based on a “one person one vote” logic: an edge in the codes co-occurrence network is only counted once per informant. When we reduce the network, we filter it, so that only edges representing associations made by, say, 4 or more different people remain. This way, associations that are made by Hildmann alone are filtered out: those that remain are those that he shares with others. The technique is explained here.
