Just a heads up since this doesn’t seem to be common knowledge. There are a lot of different services. You can search “residential proxies” or “clean ip address vpn” and similar. Not sure if I’m allowed to name the names of services, but the one I use (not affiliated, just been using it for a few months now) has a US VPN option for $10/mo BUT there’s a $20 setup fee. Similar prices for other countries I think. If you use some of the shadier services that use browser plugins and desktop apps to “loan out traffic” then you can probably get them a lot cheaper. Just don’t install anything from the shadier ones, use the VPN config files.
There are websites for that, which get used all the time. Basketball, football (NFL & college), MMA, hockey, football (soccer), motor sports, baseball, boxing, etc., along with Firefox & uBlock Origin. Never had a problem, unless it’s been a lessor known boxing or MMA match by a smaller promotion.
