Leo has been trying a new DNS service called NextDNS. Not only does it keep your online activity private from even your ISP, but it also blocks ads and has great parental controls. And it's free for most types of online activity.
Online ads have become increasingly pervasive and annoying over the years, so the effort to circumvent or block them entirely is no surprise. Some ads go as far as to completely obstruct content, and it can significantly slow down the responsiveness of the site as well. Some sites automatically start playing video and audio of ads or other content, which can interrupt something else you’re watching or listening to. It may seem like an obvious solution to install and run an ad blocker all the time, but this presents an ethical dilemma.
