That’s not the kiddo’s fault.
GitHub should have a feature when you tag a group, it should show how many people will be notified and ask for confirmation.
Anyone will be afraid if they see a warning like “This message will notify 400k people. Are you sure?”
Why would GitHub let a random person notify 400k people? Maybe I'm not fully understanding this. I've never really looked into limits around @'ing people. Could I just open a random PR and @EpicGames/developers to notify 400k people just to annoy them? Why doesn't this happen non-stop?
How would be your business model without ads if you owned YouTube then?
As a video platform owner, you should pay creators, you should pay for all the server costs which is capable of 4k+ streaming, besides you serve all the music and pay royalties.
Mobile stores are different. If Google explains details, they will understand how google found out so they will develop better tactics to not be banned next time.
Then Google will just have to work harder. Banning legitimate customers over automation failures is not a thing that should be considered acceptable or legal.
