How to stop youtube app on android

Question

YouTube

what can be done so that a person cannot watch YouTube through the application, and at the same time does not understand that there was some kind of interference? IF NECESSARY, I CAN TAKE THIS PERSON'S PHONE, BUT IT IS PREFERRED THAT THERE IS SOME REMOTE METHOD. I tried to blacklist YouTube addresses in the router settings, but at least the application had something.
Please help, I can't do this anymore!!! all the wife’s relatives from the village come for a week (four people and a chihuahua. I won’t be surprised at all if this rat with a smartphone comes this time) and all at once, having reached the normal Internet, they start watching YouTube, 24/7 at 1080. also through the speaker at full volume.
at least cut the internet cable!

Answer 1

Limit the speed on the router. The application will work, but it will become impossible to watch YouTube due to brakes and video uploads. Especially in 1080.

EMP - an electromagnetic pulse, cuts down almost all electronics in its radius of action. Brace yourself man! I've never been in such hell, but I understand you perfectly...

Answer 4

You can win that too. Any computer in a local area network is necessary. Alternatively, a virtual machine. We put on it any web server and dns.
On the web server, we saw any stub. It is necessary stupidly for what would be.
Important - the name and aliases of the site must be YouTube.
On the DNS server, we prescribe that YouTube is on the server.
On the router, specify the local dns (in the network settings). DNS address - server address. And the second dns. For example 1.1.1.1
Outcome - people requests the site. The router tells the chela that he needs an internal dns. Because he is the first. If dns knows the site, for example YouTube, then it leads to the address specified by it. Does not know - leads to another dns, which knows.
If you wish, you can block any site locally in this way)

Answer 5

If you have access to the "victim" account, then you can temporarily add it to your Google Family. Specify her account as a child account and then a lot of settings appear that can be done remotely. You can stupidly hide YouTube from the list of applications, you can limit the working time, limit the viewing list (you can set an age rating for the smallest and any search on YouTube will give only Malysharikov), etc. When he leaves, remove from the Family.
