Another possibility: The domain was registered in China, possibly with a registrar that won't shut it down if its get mass-reported, while using an anonymizing service that hides the registrants powerwords and dox.
The shift in attitudes over time is definitely real. There was a time when misbehaving students that got sent to the office were looked at with disdain by their peers because being sent to the office was clearly the result of bad behavior. Now, that's frowned upon as shaming, and parents/guardians are quick to white knight their trouble-making children with a quick, "Not my little precious angel!" while threatening to make everyone involved's lives miserable for daring to discipline the student.
The worst part comes from someone I know who until recently was a permanent sub. At one point she told me how the kids act even more outrageously once they learn that there are no consequences for even the worst in-class misbehavior. She even stated she's had students boldly tell her, "You can't stop me/make me," because they know the worst they might get is a metaphorical slap on the wrist before being sent back to the same class they came from.
Tying into the ongoing riots, a lot of these protestors grew up knowing they had no consequences for their bad behavior because their helicopter parents would take care of things or make the issues go away. The enjoy the same treatment in places such as the PNW region where DAs with ties to Antifa release arrested protestors on their own recognizance and drop all local/state charges against them no matter how serious they may be. The net result is that the protestors feel more emboldened when they return to their protests the next day and often double/triple down on the same criminal behavior. Look no further than the video posted some time ago where the police identify a protestor by name because they've been arrested and released so frequently.
