His example is a bit confusing, so I'll just elaborate. Context matters, but only in terms of your intent.
Irrelevant Context: They called you something with the intent of verbal abuse (not just banter); You retaliate with the same. Your punishment will be justified. The context of what others did to provoke you does not matter. The context of you had intentions of verbal abuse does.
Relevant Context: The enemy Lucian escapes with less than 50 HP for the fifth time in the match. You type "/all Just fucking die already!!!". This would not be punished, and if it was you would have a strong case to appeal it. The context is that your intention was to express your frustration over him surviving, not to verbally abuse him or want him to die irl.
