Welcome to Webmasterworld, mikefemi100!
Many WYSIWYG editors will insert a "meta" generator statement in the head element revealing who shot john. Some create extraordinarily complex Span elements for text styling and thus reveal it was not hand coded.
I've never been particularly concerned about this as I hand code everything... but it is an interesting question. Hopefully others will have more to say.
