This is a Fandom wiki, not a standalone business or online store. Gameofthronesfanon.fandom.com is a community driven fan fiction hub for Game of Thrones content. Because Fandom is a well known hosting platform with established security practices, the site itself isn't a scam or a phishing trap. It uses modern encryption and browser protections that you would expect from any legitimate website.
The main thing to keep in mind is that anyone can edit or contribute to a Fandom wiki, so the content quality and accuracy vary by community. There is no product to buy, no payment forms to fill out, and no personal data collected here directly. If you are searching for gameofthronesfanon.fandom.com reviews to see if the wiki is actively maintained, the lack of a WayBack Machine history and its low traffic rank suggest this is a small, possibly new community. That doesn't make it fake or dangerous, but you should check whether the content is up to date to your liking.
In short, is gameofthronesfanon.fandom.com safe? Yes, as safe as any user generated wiki. Treat the content like you would any fan forum, and you will be fine.
