I just checked a variety of vulgar terms and I can confirm they’re not censored on PC, just on iPhone. However, I somehow had in mind they were censored on PC, too, at some point.
Censoring them on the iPhone is probably related to App Store policies though
Indeed looks like there was an issue with the styling on web.
Will fix this now so that the NSFW settings work properly.
Thanks for bringing this up!
PS. Because JMDict gives us limited info/is innacurate about a words true NSFW status, we basically just have to be very strict and blur out anything that could possible be NSFW.
This unfortunately includes harmless colloquialisms and slang.
Basically some very very NSFW words are marked with the “colloquial” tag but not the “vulgar” tag.
Very annoying.
