Tech foul question

[NoFussRef]

Our HS Rec League follows the "3 unsporting T-fouls on a team= forfeit/game over" rule.

What does a pregame/halftime dunk T-foul fall under?

I whacked 2 players same team a few seconds apart during halftime for climbing the net/rim-hanging dunks. (thats 2). Later we had 1 legit unsporting T on same team.

We allowed the game to go on as this was 2 teams from same HS and was more like a friendly scrimmage than anything else. It was actually the best sportsmanship and behavior from both teams all year. But for sake of argument is a deadball dunk "unsporting T" or something else?
