What is the cattle prods method?

Poking unruly children with an electrified goad stick. https://en.wikipedia.org/wiki/Cattle_prod

Omg! This is hilarious! Are you allowed to restrict their library time if they misuse it or are disruptive?

Yes, and the threat of terminating their computer privileges for a day is really far more painful to them than any electroshock devices ever could be.

That's good! I think you're on to something then. Have you brought this idea up to the attention of the other library staff?

It's standard library policy regarding that kind of disruptive behavior.

That's good then. Are some of the staff members not holding the kids accountable. Is that the issue?
