Ask HN: Are these videos from hacked IoT devices?

Many videos now contain everyday video backdrops. I saw one the other day that was just chickens wandering around. I'm sure they are there to prevent copywrite bots from discovering IP theft. That is just my best guess though.

If not, what are they?

I am referring to the videos with IMG and then 4 numbers in them. They are various scenes of asian families doing things in their houses.
