The timer is edited in by the runner. However, every run - whether it has an edited timer there or not - will be retimed by the moderation team.
That's not as unlikely as you think it is. Since your video is 30fps you just have to make the kill within a 33ms window which is actually not that rare
That is completely up to you. You may leave it empty or just add the second player's username.
As long as the footage shows no cuts between the command being run and the game you want to submit, it's completely fine to run the command in the lobby.
Zooming in is not a bannable offense, you can verify that for yourself on this website.
Also since I am a moderator for this page, I can verify my own runs. If I were to cheat any of my runs, I would of course be stripped of my moderator role and my runs would be banned from the page. However, as I provide video evidence for all of my runs, you can hardly find any evidence of cheating. You are welcome to try though.
My main role in the moderating team is verifying Gravity runs but nothing is stopping the other moderators from also verifying.
Usually that would not count but since there is no visible instance of teaming here to get a faster win (since the game only lasted half a second) and this is also not a top 3 run, this will count
The fastest time in a public game that I know of is a 29.7
There was a change in the reset update that changed how unstucking works. You get the unstuck button by idling in the water (or on an island) for 30 seconds. This was used a lot throughout the course of the full game runs which is why the boards were reset. The condition for them to reset is if there is a change that is so significant that you can't reproduce a run which was done in the previous update in the new one. You can still look at the old categories to see what I'm talking about.
P.S.: If you try to unstuck now it will send you back to the Raft which is what was changed
