Something I have wondered for the longest time, how does the community feel about other people using someone else's character fantasia? Is it wrong? Is it thief?

I'm sure we have all been there where we met a clone that could pass off as our twin brother or sister, or have even seen a character we liked so much we wanted to borrow features from them.

So my question is simple, what are your opinions on players wanting to use someone else's fantasia without asking?
