Hmm, having a look at the post history, the majority of it was in the German boards, but when the forum came back online, I noticed a sudden change on the posts of this user: it appears that his English is not bad at all. Also, the account became active again since its last post in 2012, and looking through the history of this forum, there are several compromises on the forum's security causing to have some down time. Could the account be compromised too? I don't know.
