Welcome to the site. I suspect a message to the mods would get a more informed view, but I don't see any adverts. And I'm using Firefox.
However, I have no idea how the site is set up - there may be some sort of link to account status, so new users see the ads, long established ones don't.
Or it could be that you have managed to get some sort of plug-in or virus installed on your computer which is serving the adverts???
