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.
This ship sailed long ago. There's no point in trying to appeal to those that are intolerant of the existence of fetish content.
