Progression of sanctions

[Scrapper1]

In USAV, the progression of sanctions starts with a verbal warning before issuing a yellow card. In a club match last weekend, I had a boys' match in which a player completed a kill stepped back from the net and then yelled through the net directly at an opponent. I don't think he was talking to him, just yelling (like "YEAAAAAAHH"). But it was clearly at the opponent.

I carded this. In your opinion, should this have been the player's verbal warning instead? Once I give the yellow, that's it for warnings on that team. But it seemed like too much for a verbal warning.

In your honest opinion, should a non-profane yell across the net get a card or a verbal warning? Thanks for your thoughts.
