Travian is always talking in their own favor. Again all comments made are contradictory. I had a discussion at the beginning of the year about showing private data on youtube. I got an answer in a mail where Travian stated that an avatar name is not private data. The screenshot is from a mail I received back on this topic.
If I read this statement above, Travian is allowed to post an avatar name and tell what decisions are made e.g. on a suspicion of a multi account. This are their own words.
