Poorly Formatted Articles are articles that do not adhere to the quality and appearance standards found on this Wiki or the standard cross-site guidelines.
These articles interrupt a user's reading flow and greatly limit the amount of information that can be included on the page. Because of this, many articles in this category will also be stubs.
The best way to fix this issue is to implement the missing elements into such an article and restructure the data.
For a more specific reference, you may check this Wiki's Design Guidelines (coming soon) or other non-stub articles without this category.
