All I can see is a kick button, which temporarily blocks them from rejoining, but does not completely ban them. I tried /ban but the command does not seem to exist. How do I accomplish this?

Edit: Can you whitelist and theoretically “ban” someone on Minecraft Realms?

Better Method

An anonymous user has suggested this new method, which sadly I can't give credit for because they are anonymous, but it's a better idea.

Have a repeating always active command block with:

/kick @a[tag=banned]

You can then run this command to "ban" them:

/tag A_USERNAME add banned

To unban someone:

/tag A_USERNAME remove banned

A workaround way to do this without the whitelist is to have a repeating always active command block with:

/tp @a[tag=banned] 0 253 0 facing 0 255 0

Make sure the chunk at 0, 0 has been generated or use a different (X, Y)!

You can then run this command to "ban" them:

/tag A_USERNAME add banned

To unban someone:

/tag A_USERNAME remove banned

This method works by repeatedly teleporting the banned player high in the sky. This makes it impossible to do anything (assuming they're not hacking), as they will also be facing upward.

Sadly you can only ban or unban someone if they are online though (Once they are banned though if they leave and join they will still be banned).

There is unfortunately no way to ban players currently, but there is a way to whitelist, so if you only want some people to be allowed on you can turn the whitelist on and add the players you want to the whitelist.
