It's an easy fix. Turn the google ads off. If you want to sell advertising, do it the old fashion way and call Yamaha, Bridgestone, Revzilla, etc, and make your case on why they should advertise on your site. Right now, with the traffic that's here, I don't think you could make the case for that, hence the google ads.
Turn that crap off and create an environment that's not a pain the ass to visit and more people would visit. By not fixing it, you're just circling the drain. More and more people will stop visiting.
But none of those decisions are made by us folks, including the admins. I'm pretty sure the person in charge doesn't know what a Yamaha FJR1300 is.
