If I had to guess, they are trying to hide the fact that they were hosting illegal material on their site. Oh, and they didn't just park it, they changed the nameservers on Oct 12 back to the default ones. The domain was created a little over a year ago and still has almost a year left.
I do not browse the forums regularly anymore. If you need me for anything (asking questions or anything else), then PM me (be descriptive in your PM, message containing only a link to a thread will be ignored).
