The expressions “No interest, No anti-fans” and “No popularity, No anti-fans” do sound like they may have been created by non-native speakers. While the structure is clear, these phrases feel less natural in English compared to something like "No expectations, no disappointments." Native speakers might find the phrasing a bit awkward because "anti-fans" isn't a common term in everyday English. You could make them sound more natural by rephrasing them slightly: * "No interest, no haters." * "Without popularity, there are no haters." This brings them closer to common English idioms while keeping the original meaning.

If by 'anti-fan' you mean people that watch something/discuss something/follow something, but they are only angry and hateful towards it, then we would usually express that as 'haters' in English. We have terms like 'hate-watching' where people watch a TV show or some kind of social media content, but they do so only to react negatively. It's a part of outrage culture that uses negative emotions/reactions to enhance engagement.
