Prowlarr has listed in its default indexers a domain that reminds me a lof of another domain that closed in the last few years, but it’s clearly a revival using the same name and adding an article behind it. I don’t want to risk downloading from it but it looks well made and legit and responsive and well kept, basically too good to be true.
So, what would be your strategy to see if it’s good? Also, there’s a discord. But the discord disagrees with Prowlarr on which should the real domain be.
I always look at the site’s Wikipedia page, gives the correct url in its summary on the right of the page.
