Actually, I saw a lot worse than this back when I played at the Hampden Rec Center (inner city Baltimore) back when I was a kid in the Sixties.
We used to have a rule: It’s not a foul unless the offended party is down and bleeding.
And we also had our own methodology for dealing with guys like the fat, bearded boy: punch the living crap out of him. Worked exceptionally well.
I played combat b-ball as a kid with no officials and used those techniques. But that would be “retaliation” on a high school basketball court with approved officials and would have gotten the fouled player thrown out. Either officiate and pitch the bums or quit taking the money. I officiated football, basketball and soccer at the high school level and soccer at the NCAA level. You walk on the field or court and take control and you are the king. That kid and his coach would have been getting a lecture from me on the 1st foul and been gone on the second! But then I am a crazy, combat veteran!
