Is this allowed? Horde spamming racist macros.

This rogue ganks redirdge all day, which I know is fine but he spams all types of macros, some racist after every kill such as "N I G G A" "YOUR AN EVIL KOREAN" "YOU LOVE ME" etc.
Some pics of him doing it.

When I asked him to stop spamming the macros, this is what he told me.
