Good obfuscation uses multiple techniques to conceal what's happening. This program uses only a single technique, and it uses it consistently. It might actually be more obfuscated to leave the letters that are also valid hex digits unencoded to confuse people about the meaning of the "digits":
print "\x4a\x75\x73\x74\x20a\x6e\x6f",
"\x74\x68e\x72\x20\x50e\x72",
"\x6c\x20\x68ac\x6be\x72";
japhy's Obfuscation Review looks like a good place to start to learn more about obfuscation.
Update: Deleting the text of a node with replies is frowned upon because it obscures the context of the replies. One option if you want to retract all or part of a node is to enclose the retracted text in <strike> tags.
