|Lionel Richie, the new face of obfuscation|
Text obfuscation is not about changing "a" to "à" as it becomes revertable easily (like we see at obfuscator.uo1.net). Spellfucker's method uses random replacements which makes the reverting process more difficult. The cool thing is that the text still stays readable.I added it to the list of More Tools in the sidebar. Via Detroit Steve.
Obfuscation 101 here.
