I’m not sure if the concerns of the “ghost town” in the original post can be resolved by having non-registered viewers see a bunch of NSFW posts.
99% of the posts here are NSFW (I wouldn't be surprised if that wasn't an exaggeration), so someone visiting the site for the first time would only see the other 1%. Given how few of SFW posts there are and how they don't tend to have much interaction beyond the occasional comment or two, it wouldn't be unreasonable for them to assume that this place is pretty much dead. By showing NSFW posts by default, new users would get an accurate measure of how active it is here and would be more likely to stay (and (hopefully) less of them would be scared off by extreme content than would leave due to lack of content).
Honestly, I'm not sure why the NSFW Lemmy UI removes the blur and auto-expands posts in the first place (though the option to automatically do this is appreciated). Reverting these is a no-brainer IMO, and it would bring the experience in line with vanilla Lemmy after creating an account (and enabling NSFW posts).
