He just a native Indonesian.
Which firstly needs to be confirmed by someone from that section.
Already cheated a lot of translation campaign with google translator. (cheated Danish translation)

I think Lauda shall tag him with negative trust.
I haven't checked all the posts from the user (mostly the threads started by him), but it may be possible that the account has changed hands in the meantime. It is highly unlikely that the user is a native Indonesian and knows adequate Skandinavsk for doing translations. However, as I am not familiar with the language at all, I'll require someone who actually knows it to review the users translations before I make a move.
