On Drupal.org they use a forum plugin for their forum: https://drupal.org/forum/22 I think using Drupal and not using a forum plugin when you want to built a forum but trying to do it your own way, counts as not using existing components.
You seem to have very weak evidence that they actually did this. It seems tremendously unlikely to me. Drupal comes with a forum module and it has many third party forums available. I see no good reason to think that they failed to make use of these resources.
The forum on Drupal.org looks I expect a forum to look. I would disagree with a few design choices but there’s nothing that looks obviously wrong.
It might be that it’s just a wrongly configured plugin but the UX decisions like the one about the fontsize of the register/login of the existing website just doesn’t make sense for the purposes of running a forum.
