the query syntax used to generate this data is based on parent_permlink which means they used it as their first tag and the tag becomes the part of url.
I did it in purpose actually, to see which people were putting Aceh as their first priority tag on their posts.

Nice :)

For additional information, you can use steemsql. Or you can read here:

Steemsql is no longer free, I am using steemdata right now, two different projects but with the same goal (gasien that mantong lon disinoe). I am also able to produce data as per mentioned on the link above.
What makes steemdata is morepainful for beginner because its database is a noSQL paradigm.

In this post, I use a different approach, what I wanna see is posts created with tag Aceh as their primary tag.
What I learned from this finding, the uses of tag Aceh at first wasn't intended as a 'bond' for users from Aceh.
You must look this post by @clayop at 2016-07-27 14:18:15.000 GMT +00.00 in here that created by design as a base for Korean people. No wonder this tag has become the 4th most popular tag in Steemit (unless you know the Korean language, you need to use google translator to understand the message hahaha).
