@AdamHeeg please note that on all sites comment threads that are getting too long are handled either by the mods or the community. This is even prompted by various automatic mechanisms. As comments are temporary by design, simply deleting them would in theory be covered by the network’s rules. Moving them en block to a specific chat thread is purposely done to preserve them and to allow a continuation of the discussion.
As this migration can technically done only once, further activity should happen in said chat room, not under the original posts.
