Look at his source code. It's a simple javascript
:eval code, once again.
It's not even double encoded except for the javascripts in the header (which anyone could paste into a decoder, found across the internet). FireFox's DOM Object Inspector can let you export the generated xml of the body. The other features - (supposed) link masking, and anti-right-click, unselector, unprinter and the 'screenshot button detector' (which probably only works in IE, or at least not firefox) are simple javascripts in the header, probably taken from various online depositories.
Source encryption, unless you've got a really good custom encoding system, just isn't worth the time. If someone wanted to steal your frontpage-5 masterpieces, there's not much you can do to stop them.
Your content? They could..
- Type it all out manually
- Decode the source
- select and copy
- take a screen shot, then scan through an OCR (this is getting serious here)
