I did this for years during the early 2010s, but given the IP ranges of most the major VPS players are widely known, many sites and services now just block them outright. It got to the stage I had to stop doing it. I suspect it has only gotten worse now many sites are trying to prevent scraping for AI training as well.
If your primary focus is just reaching region blocked content, Self hosted VPNs can work great if you have access to a residential IP in your target country- I've taken advantage of family member's domestic connections instead of VPSes now, as I was lucky enough to have family in the regions I wanted. Devices like the Apple TV can function as a Tailscale exit node too, which greatly simplified deployment.
