This question references https://www.dndbeyond.com/, which is an official WoTC website. The problem we face with this content is that it is not accessible without a twitch account (afaik).
This defeat a huge part of this stack exchange. We could avoid this website but since it is seen as official, we would lost a lot of content. A solution could be to enforce to include the meaningful content into the post.
What is the policy about link targeting locked content?
