Dev here: Unfortunately, that was one thing I never managed to figure out with WikiTok - content filtering. Wikipedia has no categorization of whether or not their articles are NSFW (imagine how much debate that would require for millions of different articles), nor something I could use in their API. That said, anecdotally, I have found the percentage of rather NSFW articles to be quite low all things considered so it's been mostly fine. I think the best option would be to have a quick disclaimer before your scroll, but nobody has seriously asked me for that.
