Nah, I’m of the opposite perspective on this. Keeping NSFW stuff login-gated is a slow death sentence for the site. The change to show it to everyone seems (to me) to have resulted in a slight increase in new people posting, and probably puts us above replacement level instead of below. I don’t have actual numbers to back that up though.
The only change I would make is to the initial content warning popup for logged-out users. Make it more specific to burggit, and notify people that by creating an account they can filter the more extreme content. A booru-style default filter that you can change or disable without logging in would be nice to have, but would be a much more difficult change to make. Even then, I’d only have it disable auto-expand for posts from the more extreme communities, rather than hiding them entirely.
