I’ve used Transmission + PIA for several years now. In that time frame, I’ve had three separate ISPs (due to moving a few times). I received a total of one DMCA notice in the last ~10 years, due to unknowingly running Transmission with the VPN off. Since then, I keep the advanced kill switch turned on.
My Google account is always logged in. I only use Facebook for their Marketplace, which is seldom.
I have no issues, at all. Keep in mind, you’re small potatoes.
