Jailbreaking

Hi everyone,
I found this website www.ps4jailbreakk.com/

I would like to know if it's true. Is it safe? Is it a scam?

If you have any information, I would like to know, please.
thanks

EDIT: Sorry, forget about the websit. I didn'T pressed the download button. Now that I did, I see that this is a scam -,-
However, does anyone heard anything about jailbreaking?
