In my experience, private schools are much more likely to expel someone than public schools. At my private school they tried to work out who was writing prank reviews of the school online and threatened that they had requested the users IP from the review service. I'm guessing they failed when the IP was just the schools shared address.

Legally, private schools arr less constrained, because due process rights don’t apply.

And why would private schools be better in this regard?
