I'm going to say that chat violations do not count, since that's a low-hanging fruit.

I'll go first. Since I'm in my house rn, really all I can do is wait for someone to come by and repeatedly toss my trident at them. Even that's not plausible bc the nearest player is 2,000 blocks away.

You have 20 minutes to get yourself banned using only the materials you have on you, without leaving the chunk you are currently standing in. What do you do?
