Why on this site

When you go to this topic,under the "why on this site " and under that is general Discusion,the add is theire all the time,it does not change,just keeps scrolling and the same info and showing the same GM cars.The advertising is for GM canada.I am trying to get my buddy who is a IT tech to see whats going on?Any thoughts.And a nother thing,no other site has this problem,if it was a problem on my end,any site I would go to would have some type of add?
