If you want to serve up ads on you site, make sure they're relevant, they're absolutely 110% malware free, and respect my privacy. And unless you're willing to take responsible for when those conditions aren't met, then don't whine when I do everything technical to block out the useless malware laden offensive ads that you do serve.
The difference between net ads and tv ads are that tv ads cost enough money that people who buy tv ads spend time and energy in being very selective about their market demographics and the type of ads they run. Plus I've never had a tv ad infect my tv and stop it from going to any other channel but CMT.
If me and my eyeballs are going to be your product, then I want a little respect for my participation.
