It doesn’t say it was created in Indonesia, it’s tagged as being written in the language Bahasa Indonesia. When you post or reply, there’s a combo box to select the language. If you don’t select anything for a reply, it will follow the language of whatever you’re replying to (hence why your comment that I’m replying to is tagged as Bahasa Indonesia, too, but I’m marking this reply as containing English).

The bot for some reason tagged the post as containing the language Bahasa Indonesia.
