Hello!
All edits must be constructive! If they are not, then a rollback or admin will have to revert the edit. The same goes with creating articles. If a user is to create a nonconstructive, speculative, opinion-based, or otherwise of no use, they will be warned and the page will be deleted until one of better quality can be created.
If a user is found constantly making nonconstructive pages, the user will be talked to, or depending on the admin, even blocked for a short period of time (2 hours or a day, likewise). To keep the wiki clean, new editors must make sure all edits are useful and otherwise constructive. This is to keep the wiki clean. Thank you!
Happy editing!
