I actually haven't turned off my ads. I usually don't come across any that are too bad. I have firefox keep the pop ups away, which is what annoys me most.
I've been clicking the ads on this site now and then if they are half way interesting. The sites running the ads can tell how many people go to their site from this forum. So if they see people coming to their site from smith-wessonforum.com, they will be happy and that will be better for Lee.
