And there it is, folks.
I added the Roku and Samsung TV servers to my blocklist months ago, (maybe even years ago, at this point?) My three smart TVs are the most blocked devices on my network, by far. It’s not even close. Here are today’s stats from my pihole:

For reference, my phone (my most used device) is number four on that list. My three smart TVs (two Rokus and a Samsung) are numbers 1, 2, and 3. I haven’t even watched TV today. These blocked requests are simply from the TVs idling. Smart TVs are hilariously, mind-bogglingly invasive, and you should block them ASAP.
