Can you check your server logs and lets us know the IP address that uploaded the files? I'd bet anything it's from asia/pacific rim or northern Europe.
I have Sammie looking into this to see if she can help find out some more info. I can not believe someone would give this blog a negative vote..gees some people on here really need to grow up. We started going through my account and deleting the files but there seems to be a whole lot of them so the company that runs the server will help. I just want all people to know that even if the script asks for folders to be 777 DO NOT do that!
