I came across somebody that uses a character that looks a lot like one of mine. It has a slightly different hair color and some spots are in other locations, otherwise it's identical to my character. I don't know how to handle this situation. Do I confront them about it? Should I notify the FA staff? I didn't think I would think much of a situation like this but it is quite upsetting I found. I don't feel that good about them using "my" character like that.

(Their prices are cheap though. Perhaps I could commission them a drawing of my character which they're already experienced in drawing. (However I don't trust them since they're the kind that steals characters... unless this is somehow a massive coincidence, which isn't likely at all.)
