This command should be available for every person. A lot of kids play this game and they simply have no money for donating.
Before I donated and muted all the annoying noobs I really had a hard time with the chat because a lot of shitheads wanted revenge for killing them, spamming shit, abusing and so forth.
Moreover, toxicity would disappear because all the rage kids will be ignored and sooner or later they will talk with themselves in the chat all alone not being visible for others.
Being ignored is waaaay worse than being muted for day/week/month because u stop exist for certain amount of people forever.
