I don't think the lemmy.ca admins or most of it's users want the instance to take on the responsibility/experience of being an instance where there's a prescribed view of acceptable and unacceptable (banned) content, above and beyond objectively objectionable stuff. Curb appeal as an argument doesn't sway me. But if curb appeal or who we're attracting is a concern, I'd point out that most of the posts in that community are very downvoted, so to some extent Lemmy's existing checks and balances are working as intended to limit newcomers' exposure to a less popular community
