what device are you using? its possible a dodgy ad may have got in, in any case Android devices do not work with Adobe flash at all it seems… I put on adblockers everywhere when possible simply to keep this crap out and when I do get ads it seems that Google genuinely think I’m a middle aged Dutch farmer and radio pirate who moved from Groningen to East Anglia – as some of the ads are stuff like “mature dating” and treatments against baldness (which plagues the Dutch, who are so tall their head goes through their hair. This is also why Dutchmen often have really strange hairstyles, to make use of what they have left…)
