You have to ask Fandom staff to enable the Abuse filter extension, but you need to have a good reason and your idea may not qualify. They tend to reserve it for wikis that have frequent vandalism and restricting editing is unlikely to convince them.

See Help:Extensions. You can always try and ask to enable it via Special:Contact/general.
