Fandom is not a social media app; it's for content creation for the most part. That's why there aren't chat-only wikis. Making messages private would make it harder for moderators to moderate and for other users to report to moderators.

User profiles are public by definition. Message Walls are a different feature (some wikis don't have it). You can submit your idea to Fandom eventually. I don't get how my number of posts is related to my privacy though.
