If you're asking whether voice-actors-from-the-world.fandom.com is safe to use, the answer depends on what you're doing there. This is a fan-run wiki hosted on Fandom's platform, not a commercial site asking for your money or personal data. As a source for voice actor trivia, it's probably fine — but you should treat it like any other anonymous wiki where anyone can edit the pages.
Looking at the technical setup, the site has decent security with HTTPS and modern encryption. That's standard for anything on Fandom. The bigger question is trustworthiness of the content itself. There's no way to see who runs this particular wiki, no about page, no contact form, and no history in the web archive to show how long it's been around. Those are all normal for a small hobby project, but they also mean you can't verify the editors' expertise.
If you're just browsing for fun, there's little risk. But if you're using this site as a reference for a project or casting decision, cross-check anything important against IMDb or official agency sites. The biggest concern with any fan wiki isn't malware — it's accuracy. Treat the information like you would a Wikipedia article that might have had fewer eyes on it.
