Did you ever experience deleting players but they still harass you?

I wish we have /ignore (nickname) command.

So if we just want to ignore deleted friends or anyone who keeps on sending us message while playing we just have to type -> /ignore (nick)

I want to suggest these commands:

/ignore (nickname)
/invite (nickname)
/join (nickname)
/boot (nickname) (reason) example: /boot player full sorry
