iPod touch ipod settings, Advanced settings question

[Jball5]

I was playing around withmy ipod lastnight and noticed that in 'settings' there is an advanced settings and in advanced settings theres 'website data', I was wondering what exactly this is, I thought it was another form of my website history but theres websites in 'website data' that I've never visited.
But I've also let my friends borrow it. Could there be websites in 'website data' that I've never visited or is it all websites I've been to in the past?

I know how to clear 'website data' but im a little concerned because there are multiple pornographic websites in my website data... I dont know if those were just spam or if someone visited those sites on my ipod...
Can you tell me if its possible to have webpages that you havent even visited be in your website data ?

They may be the info from banners on pages that you did visit.

Really? Because theres so many of them and on the side it says like 3.2 kb and 2.2 kb, would that be too much memory or whatever to just be a banner? cause some are tiny like 92 bytes but 3.2 kb seems like alot, maybe not? I do go on youtube all the time and the number for that is 399 kb
Im wondering if someone used my ipod to look that kind of stuff up
