Strange name issues?

[yatenkou]

I just noticed there was another user called YatenKou, and I seem to have gotten all their data?
At first I thought it was a coincendence, but after I set my avatar, I noticed that all the posts by the original Yatenkou got my avatar?
Was the person previously banned, and by rejoining with their name I have gotten all their data and crap reputation?

Well, there was a yatenkou, but they left the board and deleted themselves as well quite a while ago, so that is kind of weird >_>
