You might be wondering why "ɡithub.com" is blocklisted. The answer is: it's not the real github.com, though they look similar. Still unsure? Try comparing "ɡithub.com" === "github.com" in your browser console—you'll see it returns false.

Using domains with mixed scripts for malicious purposes is called IDN Homograph Attack. It is a very advanced type of attack – and I plan keep adding relevant homograph domains here from now on, so we will help prevent people from being deceived by them.

I used a tool I created, EvilURL, to analyze the actual github.com domain. I discovered a concerning issue: some registrars allow domains with mixed character sets, enabling bad actors to create domains that look nearly identical to legitimate ones. And this malicious domain "ɡithub.com" is registered and leading to a malicious website.

You may be asking, why is github.com is being blocklisted? Well, it is not actual github.com, although they are visually similar. Still in doubt? Compare "ɡithub.com" === "github.com" in your browser console, the result will be `false`
