lib.rs: if you specify "twitter" in the request, it redirects to a third-party site

I don't know if it was or not yet. At first, I didn't understand how I ended up on the website, but then it dawned on me when I repeated it. Of course, anyone can do whatever they want with their website. But in my opinion, this behavior looks the same as a library with malicious code that activates for certain IP addresses.
