Scam site.
They're notoriously known for plaigarising Wololo.net's articles as well.
I would remove the link if I were you. You would just be giving that site more attention, which in turn, bumps them higher up the search engine results...
As mentioned, stick to the official
http://wololo.net site, which has its own (real!) news and updates about (real!) PS4 software hacks and "jailbreaks" (do people seriously say jailbreak still? Thought that was just for iPhones...)
