Welcome to WebmasterWorld Guest from 22.214.171.124
What happens when you access the pages of your site with a referrer from a search via google? Does your IP show up with the right info (referrer, ua etc)?
They asked for $300? Did they also say how to pay them?
Sorry, I was sarcastic when I mentioned "how to pay them". I am just thinking if it's a hijack it's probably a fishing email.
Search your site in google with the default settings of your browser (make sure you first set the security settings of the browser to the highest level). Then access one of your site's pages. Then goto your GA account and see if the access you just did shows a referrer. And verify it against the server log.
Also the fact you see visits on hidden or non-published pages is highly suspicious.
Setting this in Firefox is very simple in about:config so a bunch more simply set it not to.
