I honestly don't feel one way or another, overall on it?
I can see how it could make people anxious or upset though, specially if they are worried about someone trying to hound them for the character, or possibly trying to steal it. [ I have heard several horror stories about both with characters in dreamy folders ]
But on the flip side of this I can also see how it could be super flattering to know that a character you adore is gaining attention as adored by others too.
So for me personally.. I really don't mind, as long as its not someone who has a history of stealing/hounding people for their characters. ^=^;
