You can't browse the web securely if you're being served third party ads. I'm not sure why this is considered acceptable and why the onus is always on the user to find and report the "bad" ads that a site owner has no control over, but it's really stupid. I spent years browsing the web before there were any advertisements at all. There is no need for this garbage despite how many Stanford grads tell you it's totally necessary.
