Deliberate teamkill and harassment over nationality - devs, please enforce your rules!

Just experienced a completely unprovoked teamkill. I was piloting a helicopter when a Russian teammate deliberately TK'd me simply because my nickname in transliteration ("JluCeHoK") made him assume I was Ukrainian.

Right after teamkilling me, he started harassing and insulting other players in the lobby.

Harassing people over assumed nationality is pure toxic behavior. The player received zero automatic penalties or bans and just kept playing. Devs, please enforce strict penalties for deliberate TKs and hate-driven toxicity!
