You would pull up lists of normal sites, complete with links. That means that the Web page you think you re going to has a little bit of java script inserted into the html that automatically redirects your Web browser to a porn site. The search engines then index the page and treat it as if it were a legitimate link to that subject. That means when you try to leave the porn site using one of those two methods, you re really being redirected to another porn site. That s the big reason.
Web sites make their profits through advertising.
They do this by showing advertisers that a lot of people visit their site. Disable java scripts on your Web browser. Unfortunately, this also keeps you from running java scripts used on legitimate pages. They usually don t disable that button, because they believe you ll probably be too flustered to hit it. Web browsers aren t human.
