Honor Demotion after end of ranked season from one blind pick? Does that delete my ranked rewards?

This is all the chat records given to me. Our jungle kindred was trolling and literally challenging my last hits bot lane and managing to take at least half of my available farm. Why am I being punished? Virtually anything can be viewed as "passive aggressive" out of context like this, why are we getting honor demotions and chat restrictions when "mute" is a thing? Why am I being punished for being harassed? I feel I have been punished for hitting enter in chat, does anyone else agree?
