I'm sure they used to put all the old episodes online (officially, legally) but the link on their website redirects to Comedy Central's UK website, where I'm guessing they don't have the rights to show them? I'd rather not pirate
Yes, the South Park website used to have every episode available for free streaming from anywhere. In 2014, the online rights for streaming the entire South Park library were sold to Hulu for about $80 million (and last year the deal was extended for $192 million), so access from outside the US was limited/ceased, thus a VPN/proxy is required for people in countries where South Park is not broadcast (or they can find episodes on unauthorized/pirate streaming sites).
I hope you'll watch Season 19 if you've not seen it yet. And I hope you won't find the Season 20 opener underwhelming.
