Is it just me?

I was browsing blogs, clicking next blog just to browse to see if I could find anything interesting but every third click or so is bringing up porn adverts. Now I know I haven't been looking at porn(honestly) and it's not like I've been getting general iffy pop ups it does seem to be Blogger specific. I'm running a spyware scan anyway but if this is advertising it's pretty sad, if I want porn I know it's out there I really don't want it and pardon the expression thrust at me while I'm flicking through blogs.

Just managed half a dozen clicks there without a dodgy porn advert site opening(scan not finished yet either), though not found to much of interest blogwise either, I know mine is crap but fucking hell there is some dross out there.
