As a witness to this incident, your question WAS answered. Your "boy" as you put it, was warned about using political language and continued to banter Slash after his warning. he was subsequently Muted, and then you became ignorant of this.
Here are the logs between "your boy" and Slash

You can CLEARLY see multiple warnings were given. your complaint is null and void.
