The Backrooms subreddit does not need to follow the wiki, as all information there is just people messing about and having creative fun. The wiki on the other hand follows a strict Canon that is used for continuous stories that play out on the discord. So that being said, you can have all the fun you want on the Subreddit and nobody will stop you, but don't throw in random ideas into the wiki without running it through the discord first, as the people there use the wiki as a tool rather than an idea posting site.
