I'm not a fan of the practice but I don't think it's necessarily a bad thing, it's just not for me. I'll also toss in that showing up to events as an NPC is borderline disrespectful to the event, depending on who and what it is: That kind of appearance has the potential to derail and undermine an existing concept, but I will concede that I've got my biases on that particular point. A lot of hard work goes into planning and staging server events, and showing up as Someone Famous can remove focus from that.
