I can SEE what it's "capable of". My browser has this incredible whizzy feature called 'view source'.
And using it, I can SEE that your demo site may as well have a big fucking neon sign on it saying 'Hey Google, I'm smarter than you and I have just fooled you and fucked over your SERPS by replacing ASCII characters with &control codes - fuck you Sergie,I',m WAY smarter than u, ban me immediately'.
probably the most STUPID thing you can do if you're trying to get a site ranked. As you would know if you had any fucking brains at all.
