Unruly Ban?

According to a riot support employee I had been permanently banned for "Taking the time to point out other players poor behavior or gameplay decisions is a criteria we do look at for negativity."

The chat in the game I had been banned in is:

I admit I was childish at the beginning, I was repeating what my teammate said in spongebob letters and said "LOOOOOOL" because he was laughing at his own bad insults for me not ganking him.

However, I wasn't banned for that, I was banned for "taking the time to point out other players poor behavior or gameplay decisions," therefore I was banned for telling Ekko to take turrets if he is going to split push. So I was banned for discussing strategy and our win condition?
