Yep. People act like they’re suddenly safe because they switch IP addresses. All those addresses are logged and can be traced by history. Heck, even VPNs can be rendered useless if they keep logs and are subpoenaed, or you forget to log out of services that communicate automatically your IP address when you switch to a VPN. Just takes a little more effort to link the VPN traffic.
People don’t understand that the only thing between them and legal trouble is the willingness of the system to expend the effort to track them down, not that there’s any real security in the easiest methods people use to avoid detection.
