I just did a quick search for myself in Google and I'm 4th for the word "Maz" today. In the little bit of a description for my site that it shows it had "maz.met.au" and I couldn't work out where it was. I'm glad to say that I did eventually track it down and fix it.

It makes me think, If google is finding non-rendered information, maybe I could make all the content on my site invisible so no-one has to read it, unless you specifically searched it.
