This is a bit of a bug in the way that the markdown auto-linker works. Since we try to autolink things that don't have http:// in them, we look for things that might be domains. Apparently, .id is in the list of valid domain endings and we linked in. We'll look for a fix, probably to not autolink things in code or remove .id from the list since its not very common anyway.
