I'm free to block whomever I like, especially when they are being hateful and calling me vain for simply COSPLAYING. I'm not blocking to win an argument, I'm blocking because I don't feel like arguing with someone who clearly has a set opinion on being rude. Cosplaying is a craft, and is just another form of fanart. It's way for us to show appreciation of the characters and the design, and I don't really see anyone claiming the designs as their own. And I think it's reaaally weird that you neither seem to get the concept of cosplaying, but has an account named "Cosplay4", created today... Weird indeed.
