Indonesian ISPs are required to filter certain domains, but go further than the Denmark case - they also block access to third-party DNS servers. Using DNScrypt or a VPN (or hosting your own DNS on a port they're not blocking like 80) is the only workaround.

Prior to third-party DNS servers being blocked a lot of tech-savvy people were using either Google's DNS or OpenDNS anyway since they tend to be more reliable than the local ISP's (even before they started filtering).

I'm no longer in Indonesia, but I could imagine the results people are posting here would be useful to folks back home so they can adjust their DNScrypt config.
