Yeah...but...you piss off the wrong guy and they literally have the power to ruin your life. Teachers in Australia have had their profile doxxed and plastered over peadophile sites. Emails arrive at workplaces with incriminating false information. The wrong troll who takes exception to a woman fighting back can easily trace your VPN. It's best not to engage. And until they actually threaten your life, the police are powerless to do anything.
