You can use a VPN for added protection if you feel you need it for streaming. But at least every ISP I have dealt with, and I will not say ALL ISP's are like this. But I have never gotten a notice or been contacted ever for streaming sports and I have been doing it for years in multiple states (PA, OH, CA). Over multiple ISP's. Complete cord cutter about 5 years now, but I have been using non pay streaming for NHL and NFL for almost 15 years. Never got a notice or contact ever for streaming never using an VPN for it... Illegal downloads... That's a whole different story.
I have gotten a few of those over the years before I got a VPN.
