So, some immature kid from Turkey with the inability to speak any type of decent English hacked the CSSremix site. Not sure what is ever gained by doing this. Wow, you managed to poke and expose a security hole. Instead of destroying someone’s hard work why not give them a heads up instead of sticking some absolutely n00bish “hacked by” page, declaring how great you are (not!).
Hopefully the owner of the Remix has been making backups and can resolve this issue with little problem.
