Haven't checked the site and won't. I highly doubt they'll just ban someone for visiting the site.
At most if they catch someone cheating, they can look up if the IP-owner has visited the Hack-site and with better certainty ban the HaXXors ass.
I think some peeps freak out too easily. People are perfectly fine putting their pictures/info on sites like facebook for everyone to look-up, but seems the IP-address is THAT big of a deal compared, huh?
Just chill, as long as you ain't doing anything illegal, Sony won't bother doing anything to your account.
