Why on this site

If the adminastration can explain this one to me and others it would be great.
As i click onto the forums page,and read the topics,at the top of the page is a constant scrolling GM of Canada add showing all the makes of cars.Now if this was a GM site,its great,but a mopar site,Some one has dropped the ball big time here,as some one is looking dam stupid allowing GM advertising on a MOPAR site.I guess the next step is we all move over the GM site and talk about mopars,Mrmopartech
