Indonesia. The blocklist mostly contains porn sites, but the government often use it to force foreign companies to comply with their requests (e.g. putting whatsapp on the block list until they comply with the new censorship rule, etc), and also used to censor any websites that offend the government (mostly communist and anti-islamist sites). Even websites that remotely contains nsfw contents end up getting blocked. Reddit and Vimeo is still blocked, tumblr was blocked (until they banned nsfw content recently), and most surprisingly, readthedocs.org was blocked for quite a while before (I'm not even sure why it was blocked in the first place).

The block list database can be accessed here, you can query a domain to see if they're blocked in Indonesia: https://trustpositif.kominfo.go.id/
