Javascript is used.

The screenshot shows instructions for users to interact with the WebView features of iOS, not the redirect tool features.

If you open a URL from a native app such as LINE or Twitter, but you cannot redirect it directly, you will be redirected to the blog site (in Javascript) by opening a browser such as Safari as instructed.

Also, this is a guess, but URLs like https://hoge.xyz/Vc are probably meant to track the link source, not the shortened URL.

When I went directly to the URL in the specified screenshot, sorry!under construction was displayed, and I could not confirm the behavior.
So when I searched the URL on Google, I found an accessible path.
(The URL itself is not included because the content is spam.)

Therefore, when I cURL and checked the contents, it included a similar image (/A_files/pic.png) to the screen shot and a Javascript that rewrites window.location.href depending on the terminal accessed.
