No one really likes ads, but for better or worse, they're a sort of necessary evil when it comes to, you know, making money online. And while Facebook's not likely to stop sprinkling your stream with paid content, the social network announced a new plan today to tackle some of the more...questionable content that's made its way onto the site. Starting Monday, the service will implement a new review process for deciding which Pages and groups will get their own accompanying ads. That process will be manual to start, with an automated version in the future. Facebook plans to have all the offending violent, graphic and sexual content removed by the end of next week.
